The paper presents an analysis of the current state of mineral processing of copper, copper-zinc, zinc-lead and copper-lead-zinc-pyrite ores. The most significant problem for selective flotation is posed by the domination of iron sulphides over non-ferrous metal sulphides in various ores. In many types of ore, pyrite content reaches 90%; in some ores, pyrrhotite content prevails over pyrite by ...
PYRITE ROASTING, AN ALTERNATIVE TO SULPHUR BURNING M Runkel and P Sturm Outotec , Oberursel GERMANY Abstract The roasting of sulphide ores and concentrates is often the first step in the production of metals or chemicals. In many processes, the production of sulphuric acid is viewed as a by-product, while in some plants production is an important economic factor. Regardless .

Pyrite is a major gangue mineral associated with galena and other valuable minerals, and it is necessary to selectively remove pyrite to upgrade the lead concentrate by froth flotation. In this study, the flotation experiments of a single mineral and mixed minerals were performed using chitosan with different molecular weights (MW = 2−3, 3−6, 10 and 100 kDa) as a depressant, ethyl ...
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the ...

The established lead-zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression. Lead flotation collectors and frother are conditioned before lead flotation which is conducted typically at near ...

Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
