Sulfide Ore Processing « TCB Metals and Refining

Processing Sulfide Ores Historically, miners have shipped their sulfide concentrates to overseas smelters that have little to no regulations or emissions controls. However, with the implementation of the Mercury Export Ban of 2008 and the high costs of installing equipment to prepare sulfide ores for cyanide leaching, many companies are searching for alternative forms of processing their sulfide ores.

Sulfide Ore - an overview ScienceDirect Topics

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 in a fluid-bed roaster. During partial roasting in the temperature range

Guides For High-sulfide Gold Processing

17/03/2020  High sulfide gold ore refers to 20% -30% of gold wrapped by sulfide (mainly pyrite). It is better to use gravity separation, flotation, or flotation-cyanidation process. The following is an analysis of specific beneficiation tests, and introduces four commonly used gold processing methods for high-sulfide gold ores.

Sulphide Gold Ore Treatment by Leaching and Flotation

18/04/2016  The concentrate from either plant could be roasted for the elimination of high cyanide consuming arsenic from arsenopyrite ores. The calcine is then quenched, ground and returned to the plant. In fact, flotation has made possible the treating of such ore bodies for the recovery of gold. It was never possible to treat these direct by cyanide and difficult to roast ore alone because of the large

Biomining: Metal Recovery from Ores with

23/06/2013  Up to now, biomining has merely been used as a procedure in the processing of sulfide ores and uranium ore, but laboratory and pilot procedures already exist for the processing of silicate and oxide ores (e.g., laterites), for leaching of processing residues or mine waste dumps (mine tailings), as well as for the extraction of metals from industrial residues and waste (recycling). This chapter estimates the world production of copper, gold, and other metals by means of biomining

What is Sulfide Mining? Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water, environment, and communities.

Sulfide - Wikipedia

Corrosion is a major concern in many industrial installations processing sulfides: sulfide ore mills, deep oil wells, pipelines transporting soured oil, Kraft paper factories. Microbially-induced corrosion (MIC) or biogenic sulfide corrosion are also caused by sulfate reducing bacteria producing sulfide that is emitted in the air and oxidized in sulfuric acid by sulfur oxidizing bacteria.
