Gravity separation method is the earliest method that applied in mineral processing. According to the density difference among mines and the difference of gravity, fluid power and mechanical force in moving medium, mines realizes mineral grains separation by density difference, gravity separation still occupies an important position in the contemporary mineral processing methods.

Since founded in 1997, Xinhai Mining has constantly increased scientific research and technology of gravity separation method. During more than 20 years of exploration, Xinhai constantly improved gravity separation method, aims at providing customers with more environmental and efficient gravity concentration and gravity separator.

efficient sophorolipids production via a novel in situ separation technology by starmerella bombicola - sciencedirect

Froth flolation was applied to sophorolipids fermentation for the first time.At oil/SLs ratio of 0.080.12, stable froth was produced for rapid separation.Cascade separators were designed for efficient froth separation.Cell loss was controlled to 0.5% by washing method for each round of separation.Sophorolipids production reached 342g/L after 221h with an improvement of 41%.

Sophorolipids are environmentally friendly biosurfactants and hence their demand has greatly increased during last decade, especially in cleaning and cosmetic applications. However, their higher production cost becomes a major barrier for wider applications compared to their counterparts i.e. petrol-derived surfactants. In this investigation, a novel and efficient technology for the in situ separation of sophorolipids has been proposed, including froth flotation followed by recovery of entrained cells through washing. First, independent cascade separators having a pre-separator and a froth separator were designed. 75% of sophorolipids were separated in the froth separator within 12min after adjusting oil to sophorolipids ratio (0.080.012) in the bioreactor. Washing was then applied to recover over 90% of entrained cells in the froth. Finally, using 5L bioreactor three rounds of in situ separation were carried out to achieve a final production of 342g/L (normalized to initial volume) for 221h, an improvement of 41% compared to fed-batch fermentation. Besides, the overall productivity reached 1.55g/L/h. Overall, this investigation provides an in situ separation technology with controllable frothing and is applicable to an industrial scale. Also it maximizes the production potential of strain along with lowering the production cost of sophorolipids significantly.

Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost-efficient process designs.

Based on abundant experiences on gold mining project, Prominer helps clients to get higher yield & recovery rate with lower running cost and pays more attention on environmental protection. Prominer supplies customized solution for different types of gold ore. General processing technologies for gold ore are summarized as below:

For alluvial gold, also called sand gold, gravel gold, placer gold or river gold, gravity separation is suitable. This type of gold contains mainly free gold blended with the sand. Under this circumstance, the technology is to wash away the mud and sieve out the big size stone first with the trommel screen, and then using centrifugal concentrator, shaking table as well as gold carpet to separate the free gold from the stone sands.

CIL is mainly for processing the oxide type gold ore if the recovery rate is not high or much gold is still left by using otation and/ or gravity circuits. Slurry, containing uncovered gold from primary circuits, is pumped directly to the thickener to adjust the slurry density. Then it is pumped to leaching plant and dissolved in aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed directly into coarse granules of activated carbon, and it is called Carbon-In-Leaching process (CIL).

Heap leaching is always the first choice to process low grade ore easy to leaching. Based on the leaching test, the gold ore will be crushed to the determined particle size and then sent to the dump area. If the content of clay and solid is high, to improve the leaching efficiency, the agglomeration shall be considered. By using the cement, lime and cyanide solution, the small particles would be stuck to big lumps. It makes the cyanide solution much easier penetrating and heap more stable. After sufficient leaching, the pregnant solution will be pumped to the carbon adsorption column for catching the free gold. The barren liquid will be pumped to the cyanide solution pond for recycle usage.

The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated onto cathodes of steel wool. The loaded steel wool is pretreated by calcination before mixing with uxes and melting. Finally, the melt is poured into a cascade of molds where gold is separated from the slag to gold bullion.
