Flotation Of Cobalt Copper Silver Minerals

Copper-Cobalt ores - Danafloat

Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small cyanide dosages. If the cobalt is found with chalcopyrite, bulk flotation can be carried out with xanthate at pH 10, and separation made at pH 4 with an amine and ...

Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation. Without froth flotation, many of the metals and minerals used every day in our modern world would be much more expensive. Solvent Extraction Solvent extraction is a hydrometallurgical process. The process entails:

Flotation of Copper Sulfide Ores - PDF Free Download

Gold with transition elements, such as silver (gold–silver alloy), copper (copper aurides) and iron are common in most of the hypogene and altered copper–gold ores (i.e. supergene). The distribution of gold in an ore plays an important role in the selection of the type of flotation process that can be applied to recover the gold [34].

Flotation of Oxide Copper and Copper Cobalt Ores 19.1 INTRODUCTION Flotation practice of oxide copper minerals dates back to almost 60 years ago, and has been applied in Central Africa (Congo) by Union Miniere (Belgium). The process involves two basic flotation methods: (a) fatty acid flotation of oxide copper minerals from siliceous ore,

Copper-Nickel ores - Danafloat

Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails.

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone 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.

From the above, it can be concluded that sulphidising flotation of oxide copper–cobalt ores with sodium hydrosulphide as sulphidising agent exhibits a good selectivity of copper and cobalt flotation towards the gangue minerals. On the other hand, the use of ammonium sulphide induces higher metals recoveries with very low selectivity.
