Sulfide Ore an overview ScienceDirect Topics

Sulfide ores, which are generally mined from underground and often found in conjunction with copper-bearing ores, contain copper–iron sulfides in association with nickel–iron sulfides. The principal sulfide mineral of nickel is pentlandite [(NiFe) 9 S 8 ].

What is Sulfide Mining? Mining Action Group

What is Sulfide Mining? 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

The sulfide ores in the underground mine (2X ore body) contain 8.8 ppm gold, 69.2 ppm silver, 0.15% copper, 0.22% bismuth and 13.1% arsenic. Some particularly rich zones contain ore with 15 to

Extraction of Metals: Methods, Processes Involved

2021-5-7  Enrichment of Ores. Ores mined from the earth are usually contaminated with large amounts of impurities such as soil, sand, The sulfide ores are converted into oxides by heating strongly in the presence of excess air. This process is known as roasting. The carbonate ores are changed into oxides by heating strongly in limited air.

NICKEL

2022-1-15  NICKEL MARKET. Nickel products that fall into Class 1, mined from sulfide deposits, comprise of electrolytic nickel, powders and briquettes, as well as carbonyl nickel. These products are LME deliverable and have a nickel purity of a minimum of 99.8%. Historically, most nickel was produced from sulfide ores, including the giant (>10 million

2022-1-17  The extraction of antimony from ores depends on the quality of the ore and composition of the ore. Most antimony is mined as the sulfide; lower grade ores are concentrated by froth flotation, while higher grade ores are heated to 500–600°C, the temperature at which stibnite melts and is separated from the gangue minerals. Antimony can be

2022-1-2  The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
