Sulfide Ore Processing « TCB Metals and Refining

For companies with platinum group sulfide ore with valuable base metals of nickel, cobalt, etcin their ores, TCB can remove the precious metals and companies can then send the processed tailings to the proper refiner. TCB allows company representatives to be present during processing at our facility.

About this site

Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel

About this site

For sulfide ore processing, nickel has to be separated from the iron present in the sulfide concentrate. This is conventionally done in both the smelting and converting stages. To aid iron rejection in the smelting stage, the concentrate is first partially roasted to oxidize the iron sulfide. This is done either in a multiple hearth roaster or

Processing of Nickel Laterite Ores on the Rise

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the

About this site

Nickel sulfide ores are processed by heap leaching in Sotkama, eastern Finland (Talvivaara, 2011).The process entails the following: (a) open-pit mining of 0.2% Ni, 0.5% Zn, 0.1% Cu, and 0.02% Co sulfide ore; (b) four-stage crushing; (c) rotary kiln agglomeration with sulfuric acid;

Nickel Sulfide Versus Laterite : The Hard Sustainability

of nickel are found in either sulfide or laterite-type ores. Globally, the bulk of historic production has been derived from sulfide ores, while the majority of nickel resources are contained in laterite ores. The difference between production and resources is due mainly to the difficulty associated with processing

About this site

Nickel Sulfide Ores and Impact Melts is designed to emphasize concepts that can be applied across a broad range of ore deposit types beyond Sudbury and nickel deposit geology. Simultaneously

About this site

The present invention relates to a new hydrometallurgical process for recovering nickel from nickel bearing raw materials, such as sulphide flotation concentrates. In general, the process involves the oxidative atmospheric pressure leaching of nickel sulphide concentrates using a sodium chloride/hydrochloric acid based leach media.
