Mining Industry Copper Sulfide Ore and Flotation

2019-7-9  1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

Copper Sulfide Flotation - 911 Metallurgist

2016-4-13  Copper minerals usually occur in low grade deposits and require concentration prior to smelting. The method and degree of concentration depends on smelter location and schedules, together with the nature of the ore deposit. Sulphide copper ores generally occur with pyrite, pyrrhotite, arsenopyrite and molybdenite,

Complex Sulfide Sulfation Process Ores Pilot Plant

2020-1-24  The process consisted of the following steps: Converting the zinc and copper sulfides to soluble sulfates by autogenuous roasting in a fluid bed. Leaching the roasted calcines with weak (10 to 50 grams per liter) sulfuric acid solution to dissolve the copper and zinc. Recovering the copper from solution by cementation with iron.

Method of flotation of sulfide copper-zinc ores

(57) Abstract: Usage: mineral processing, in particular flotation of copper-zinc sulphide ores and products. Method of flotation of sulfide copper-zinc ores includes the conditioning of the pulp in a calcareous environment with reagents-regulators sulfur, sodium, and zinc sulfate, the introduction of collector and Frother and subsequent separation with separation of copper minerals in the ...

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 ...
