Sulfide Ore Processing « TCB Metals and Refining
Processing Sulfide Ores. Instead of relying on autoclaves or roasting to prepare a sulfide ore for traditional leaching, our vibratory grinder on our circuit allows our leach to make contact with the precious metal encapsulated in the sulfide so leaching can occur. With the aggressive nature of our leach allowing us to process most ores in an hour,...

Nickel ores are not susceptible to mechanical enrichment. The silicate nickel ores contain cobalt with the Co:Ni ratio of the order of 1:20–1:30. In some deposits, the silicate nickel ores are accompanied by ironnickel ores with high proportions of iron (50–60 percent) and Ni (– percent).
Indonesia ore ban spurs nickel to 5year high | Kitco News
The original ban on ore exports in 2014 was lifted for certain minerals in 2017 to give miners time to build smelters to process minerals such as nickel, bauxite and copper. Indonesia now only allows miners to export lowgrade nickel.

Extraction of nickel from the laterite ores Hydrometallurgical process involves ammoniacal or sulfuric acid leaching followed by nickel precipitatation. In the pyrometallurgical process the ore is dried and calcined in a rotary kiln and then smelted in an electric furnace with addition of carbon .
EXTRACTION OF NICKEL AND COBALT FROM LATERITIC .
Nickel is concentrated by rockweathering process, in other words erosion. Nickel containing olivinerich igneous rocks, are weathered and concentrated, by the chemical and mechanical activity of nature, up to a level that they can be considered as nickel ores. This process is called lateritic weathering [11, 20].

Dec 18, 2016· The major sources of silver are lead ores, copper ores, leadzinc ores and coppernickel ores found mostly in Mexico, Australia, Bolivia, Serbia, Peru, Chile, China, and Poland. Silver is produced mainly as a byproduct of the electrolytic refining of gold, nickel, copper and zinc in the ores.
HydroPyro Integration in the processing of Nickel Laterites
Hydrometallurgical process routes are seen to be the future of treatment of the lower grade nickel laterites ores. Hydrometallurgical projects of recent years have focused on HPAL and have been largely unsuccessful economi cally so far, with huge capital cost overruns.

The other nickel containing type of ore, sulfidic ore, is usually found in combination with copper ore and is mined underground. Nickel from lateritic ore is extracted trough extractive metallurgy. It is extracted from its ores trough a conventional roasting method which removes the moisture from the ore.
