recycled pulp mill planned in northeast us - resource recycling

The Empire Recycled Fiber mill is in development in Fairless Hills, Pa., on the site of a decommissioned steel mill complex. The facility will be looking to bring in 505,000 tons per year of recovered fiber from nearby regions, said Bill Moore of Moore & Associates. He presented on behalf of the project team during a recent virtual meeting of the Association of New Jersey Recyclers.

The mills output will be 440,000 tons per year of recycled paper pulp, which paper manufacturers will use as a raw material. The mill will use state-of-the-art processing technology, Moore explained, to produce and dry the pulp to 10% moisture content. Then, the material will be wrapped, baled and exported to China.

The recycled pulp mill will fill a market void left in the wake of Chinas National Sword import restrictions. Recovered fiber has become far more difficult to ship into China due to the policy actions, but pulp made from recovered fiber does not face the same import scrutiny.

Empire Recycled Fiber has a Chinese paper producer as an equity partner, and that same company signed a 20-year offtake agreement for the pulp. The project team has not publicly named the partner company, which holds a majority ownership in the Pennsylvania facility.

Empire will source scrap material primarily from eastern and central Pennsylvania, as well as New Jersey. The facility will also look to Maryland, Delaware and New York as secondary sourcing areas, Moore added.

Early work on the mill project began about a year ago, Moore said, and the team plans to close on financing during the third quarter of 2020. Full construction work is planned to start this fall and take a year to 14 months.

Project leaders are already working with numerous recovered paper suppliers, including Waste Management, Canusa Corp. and more. The mill is looking for long-term supply contracts, Moore explained, and will begin buying recovered paper in late 2021 as the facility gears up for a 2022 startup.

Moore pointed to the ongoing decline in Chinese recovered fiber imports and the likelihood that the country completely closes the door to recovered fiber imports next year. These restrictions, Moore explained, have led to an unsustainable situation for the Chinese paper industry.

They dont have enough fiber to run their mills, Moore said. As alternatives, the Chinese industrys sourcing options are to increase domestic fiber collection, use more virgin pulp, use finished products such as linerboard, or import recycled paper pulp.

The first three options are taking place to some extent but are either not supplying enough material or are financially challenging. Domestic collection can only increase so much, Moore noted, because a substantial portion of containerboard boxes produced in China end up getting shipped abroad. And using virgin pulp and finished products carries significantly higher costs than raw recovered paper or recycled pulp.

The latter option is becoming more and more popular. Chinas import restrictions do not extend to processed material made from recovered fiber, and in recent tariff talks the Chinese government lifted import duties on U.S. recycled pulp.

Chinese imports of this material from all countries quadrupled from 2016 to 2019, Moore noted, hitting nearly 1 million tons. Next year, he estimated, the country could import 3 million tons of the material.

Last year, a paper processing equipment supplier reported receiving numerous orders for recovered fiber processing plants outside China. Many of these operations have been located in Southeast Asia, where the proximity to China means fewer logistical hurdles. Pulp can be shipped in its wet form from Southeast Asian producers because the trip is short enough to avoid moisture-related damage to the material. Pulp originating further from China needs to be dried before transit.

Despite the greater distance, the U.S.-to-China model is taking off, as well. Pulp exports from the U.S. to China jumped from 16,000 short tons in 2018 to 239,000 short tons in 2019, according to U.S. export data. During the first four months of 2020, the U.S. shipped 94,000 short tons of recycled pulp to China.

U.S. mill operator Sonoco Products recently reported it shifted some of its recycled paperboard production capacity to instead produce recycled pulp, and the company has been shipping that material to China. Nine Dragons, the largest paper company in China, has purchased multiple U.S. recycled fiber mills in part to ship recycled pulp to the companys manufacturing operations in China. Earlier this year, a separate recycled pulp facility project was announced in Chesapeake, Va.

A government-convened commission of California recycling stakeholders has outlined steps to boost markets and cut contamination. But the groups report also leaves PP plastic off a key initial list of accepted materials, drawing quick pushback from national associations.

The Oregon House and Senate last week approved a bill establishing extended producer responsibility for packaging and adding other elements to the states recycling system, including new requirements for MRFs and an evaluation program for product labels.

gold processing 101 - mining magazine

Amidst the general fall in metal prices over the last few years, the gold price has remained comparatively stable in the US$1,000-1,250/oz range. Gold bulls were disappointed that the price did not break through the $2,000/oz ceiling; nevertheless the current stable price run has helped to maintain a strong interest in gold projects.

The second is the sustained, and dare I say sustainable, use of cyanide for gold leaching in the last 100 years or more in a world of increasing environmental concerns and general aversion to the use of toxic chemical like cyanide. Alternatives to cyanide are not the subject of this article, but it is suffice to say that recent applications of alternatives to cyanide, e.g. thiosulfate at Goldstrike Nevada, have been driven by technical rather than environmental imperatives. In the case of Goldstrike, this was a double-refractory ore combining sulphide-occluded gold with preg-robbing carbonaceous material that rendered the ore unsuitable for conventional cyanide leaching and carbon adsorption.

In most cases, gold processing with cyanide leaching, usually with carbon adsorption, is still the core technology and the critical thing is understanding the mineralogy in order to optimise flowsheet selection and cost drivers, and get the best out of the process.

Traditionally, the process selection choice was between a conventional, well-tried, three-stage crushing circuit followed by ball milling, or single-stage crushing followed by a semi-autogenous (SAG) mill and ball mill. The latter is preferred for wet sticky ores to minimise transfer point chute blockages, and can offer savings in both capital costs and long-term operating and maintenance costs. However, the SAG route is more power-intensive and, for very hard ores, comes with some process risk in predicting performance.

Now that initial wear issues have largely been overcome, they offer significant advantages over a SAG mill route where power costs are high and the ore is very hard. They can be attractive too in a heap leach where the micro-cracking induced by the high pressure has been demonstrated in many cases to improve heap leach recovery.

The hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle size and liberation characteristics. These are summarised in Table 2, where the processing options that correspond to the various combinations of mineral associations and liberation are shown along with some examples.

This is common in tropical environments (e.g. West Africa) and typically oxidises gold-bearing sulphides down to 50-100m, transforming commonly refractory gold in sulphides to free-milling gold, behaving in a similar fashion to gold associated with quartz.

Refractory ores are typically treated by flotation and the resulting flotation concentrate may be sold directly to a smelter (common for example in China) or subjected to downstream processing by pressure oxidation or bio-leach.

An ore containing 1% sulphur will produce a mass pull of approximately 5% by weight to a bulk flotation concentrate where recovery is the key driver. If this ore also contains 1g/t Au (for GSR =1), and 90% recovery to concentrate is achieved, then 0.90g will be recovered and with a concentration ratio of 20 (5% to concentrate) this corresponds to 18g/t Au in concentrate.

Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost environment, a good rule of thumb is that a minimum GSR of 0.5 is required for downstream processing of a gold-bearing concentrate.

A lower GSR can be tolerated if the flotation concentrate is amenable to direct cyanide leaching without the costly oxidation stage to release the gold from the sulphides. And on-site dor production avoids the off-site costs of transport and smelter charges, but usually with lower recovery (flotation recovery then oxidation-leach recovery) so a trade-off analysis is required.

Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates.

It can be seen that the key cost elements are: power, cyanide and grinding steel plus, for refractory ores, the costs associated with pressure oxidation or bio-leaching. It should also be noted that, where cyanide destruction is required (increasingly the norm), then cyanide detox unit costs are usually of a similar order of magnitude to the cyanide unit cost.

In summary, and of particular relevance to project screening, an early appreciation of gold mineralogical associations and liberation can provide considerable insight into metallurgical process flowsheet selection and processing costs.
