Studies of enrichment of sulfide and oxidized ores of

The paper presents the analysis of studies of the enrichment of sulfide and oxidized ores in Yakutia deposits. The ore of the deposit is a mixture of primary, mixed and oxidized ores. The main useful component of the studied ore samples is gold with a content of 1.5 to 2.8 gt, the silver content is low 5-17 gt. Ore minerals are represented by sulfides, among which pyrite predominates.

Study on the pre-treatment of oxidized zinc ore prior

The pre-treatment of zinc oxide bearing ores with high slime content is important to ensure that resources are utilized optimally. This paper reports an improved process using hydrocyclone de-sliming, dispersion reagents, and magnetic removal of iron minerals for the pre-treatment of zinc oxide ore with a high slime and iron content, and the benefits compared to traditional technologies are shown.

copper sulfide lead ore extraction processing

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

A Flotation Technique for a Sulfide-Oxidized Cu-Co

Conventional floatation treatment has poor effects on recovering Cu-Co sulfide-oxidized mixed ores due to the high oxidation rate and large amount of carbonaceous mud of the ores. The research results showed that the pre-removal of carbonaceous mud - asynchronous flotation process got a better flotation results than the conventional process.

EXTRACTING METALS FROM SULFIDE ORES

EXTRACTING METALS FROM SULFIDE ORES

Mixed oxide and sulfide copper ores are leached following the same process stages as in Figure 4. Also, some sulfidic ores that are too lean to treat by flotation are also leached in heaps or dumps. The recovery of metals from sulfides in this way utilizes bacteria either naturally present or inoculated into the material.
