Oxidative Hydrometallurgy Of Sulphide Minerals

Sulphide minerals are one of the most important sources of value metals, such as gold, silver, copper, zinc, etc. Due to the strong sulphur binding to these minerals, metals are usually extracted by pyrometallurgical route or hydrometallurgy with chemical oxidation. Of these, hydrometallurgy apparently has a lower environmental impact, which has

Chapter 7 Flotation Of Sulphide Minerals

are the two most commonly floated copper sulphide minerals. Bornite Cu 5 FeS 4 and covellite CuS and energite Cu 3 AsS 4 are normally present in lesser quantities. The complete flotation of chalcocite is achieved between ph 1 to ph 10 with ethyl xanthate. The resulting hydrophobic species is CuX. 1. Hydroxyl as depressant OH-

Chemometric Optimisation Of A Copper Sulphide Tailings

The presence of fine and ultra-fine gangue minerals in flotation plants can contribute to sub-optimal valuable ore recovery and incomplete water recycling from thickeners, with the performance of the latter equipment relying on adequate flocculation. In order to study the dependence of the flocculation process on the suspension-flocculant mixing conditions, a series of experimentsampmdashchosen ...

List Sulphide Minerals 911 Metallurgist

Sep 27, 2016 The sulphide minerals are compounds of the metals with sulphur. Nearly all these minerals have a metallic luster, i.e., the peculiar shining appearance of metals, such as gold, silver, copper, lead, tin, iron, etc. They are all heavy minerals and nearly all are of economic importance. Iron Pyrites or Pyrite. FeS2.
