US20150021236A1 - Mineral Ore Flotation Using Carboxymethyl

A flotation method for mineral processing is disclosed. The method for floating includes a first step of using a first carboxymethyl cellulose (CMC) in a first flotation cell, and a subsequent step includes using a second CMC in a subsequent flotation cell, the first and second CMCs having different characteristics.

Unlocking Disseminated Nickel Sulphides using the CESL Nickel

Smelting and refining of massive sulphides begins with the flotation of ore, typically in the range of 0.2-2% nickel, to an acceptable concentrate grade of 10 to 20% nickel.[2,11] Concentrate smelting produces a high grade nickel matte which is then refined hydrometallurgically. [2,12] With the majority

Method for improving selectivity and recovery in the

However, the selectivity between Cu/Ni sulphides and pyrrhotite is not improved with the addition of lignosulphonate alone in the industrial process. In this sense, the state of the art lacks a method for a) improving the selectivity and recovery in the flotation of Cu/Ni sulphide minerals which are associated with iron sulphides, and b ...
