gold cip processing solution - mineral processing

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

Activated carbon acts like a sponge to aurocyanide and other complex ions in solution. Hard carbon particles (much larger than the ore particle sizes) can be mixed with the ore and cyanide solution mixture. The gold cyanide complex is adsorbed onto the carbon until it comes to an equilibrium with the gold in solution. Because the carbon particles are much larger than the ore particles, the coarse carbon can then be separated from the slurry by screening using a wire mesh.

geovic mining corp. announces discovery of chromite deposit in the bitoi delta, papua new guinea

DENVER, COLORADO--(Marketwired - June 10, 2014) - Geovic Mining Corp. ("Geovic" or "the Company") (GMC.TO)(GVCM) is pleased to announce the discovery of a chromite mineral sand deposit in the Bitoi delta in Papua New Guinea.

Geovic holds the following equity interests in various exploration projects: a 60.5 percent interest in the advanced Geovic Cameroon PLC Cobalt-Nickel-Manganese Project in Cameroon; a 100 percent interest in Geovic Nouvelle Caledonie SAS's Chromite Project in New Caledonia; a 100 percent interest in Geovic's Chromite Project in Papua New Guinea; a 100 percent interest in Geovic's Arizona Gold Project; and a 10 percent interest in the Wind Mountain Rare Metals Project in New Mexico.

Chromite occurs as heavy mineral sand deposits along the coast of Morobe Province of Papua New Guinea. Previous exploration programs by AMAX Australia in the 1970's, OM Group and others found smaller chromite mineral sand occurrences further South at Hessen and Sachsen Bay. Geovic has been evaluating chromite sand in the Bitoi river delta near Salus, Morobe Province because of the large potential size of the deposits. Geovic's exploration license EL-1981 covering this potential mineralized area is presently being renewed.

Reconnaissance sampling of surface sand yielded elevated chromite content. The average Cr2O3 content of these grab samples was 21.6 6 wt.% and was determined by X-ray fluorescence analyses. The range of Cr2O3 content varied from 8.2 to 29.3 wt% in the best mineralized sample (see Table 1 below) based on independent analysis provided by Activation Laboratories Ltd. There has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

The location of the samples is shown in Figure 1 above. The discovery has spurred the Company to prepare for a drilling program that confirms further the geology of the deposits. The primary goal of this program will be to measure chromite grades at depth and recover sufficient material for bulk metallurgical testing. Samples will be analyzed for the chrome content in chromite and to identify other valuable products such as olivine and magnetite.

The Company anticipates that the minerals have the potential to meet foundry and metallurgical grades in the market. The foundry and casting sand is potentially attractive because both olivine and chromite would also be produced. Demand for non-radioactive, high temperature foundry sand is increasing as zircon, a foundry sand that has highly radioactive trace components, is gradually phased out.

Geovic anticipates split-tube and auger drilling to commence subject to renewal of the exploration license and funding. Geovic plans to operate its own drilling equipment in this program, and has successfully drilled similar mineral sand deposits in New Caledonia. Geovic anticipates drilling between 200 to 300 holes with a depth range of 5 to 15m in the Bitoi delta. The spacing of the holes would be sufficiently close to each other to allow a geo-statistic interpretation that could lead to a NI 43-101 compliant resource report. The Company will continue to update its stake and shareholders of progress in this program.

The scientific and technical information in this press release was reviewed and approved by Erwin Schutfort, Vice President of Geovic New Caledonia SAS (Qualified Person, AUSIMM), a Qualified Person under National Instrument 43-101.

Geovic is a U.S.-based corporation whose principal asset is 60.5% indirect ownership of a significant cobalt-nickel-manganese deposit in the Republic of Cameroon, Africa. Additional Company initiatives and project information may be found on the websites, and For more information, please go to
