roasting of copper and nickel ore and ore concentrates

US5254320A

In this inco ore there is only 1.3 percent copper and 1.2 percent nickel as low grade as that, there will be ground and there will be floatation, tailings will lose a little bit of copper and nickel. But the bulk copper nickel concentrate will have 6 percent nickel and 7 percent copper. So, we get a bulk concentrate.

Oct 26, 2012· This paper describes a chloridizing roasting process applied to two types of nickel and copper-bearing sulfide concentrates. One was copper rich and the other nickel rich. The paper gives a full account of the process as investigated in various batch roasters, and in multiple hearth and rotary roasters. For commercial viability, the paper finally examines the …

Copper processing

Process for the removal of arsenic and / or antimony sulphides from copper, nickel and / or gold containing ore particles. The ore particles are introduced into a reactor wherein a fluidizing gas is injected into the reactor to form a fluidized bed containing at least a portion of the ore particles. The ore particles are heated in the presence of inert particles to a temperature between 500 ...

Roasting of Copper and Nickel ore and ore Concentrates

Lime products play a key role in the mining and extraction of non-ferrous metals, including aluminum, copper, gold, nickel, cobalt, uranium, titanium and lithium. Lime is also important for the pyrometallurgical refining and smelting of several non-ferrous metals. In addition, lime products are used in effluent and tailings treatment, and in settling, dewatering, filtration,

(PDF) PARTIAL ROASTING OF COPPER CONCENTRATE WITH ...

A copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal. A typical copper ore contains between 0.5% and 2.0% copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal.

N. Ahern, in Gold Ore Processing (Second Edition), 2016 2.1 Oxidative Pretreatment. During roasting of gold ores and concentrates, mercury is released to the gas phase, with the extent of release dependent on the mineralogical composition of the roaster feed and on the roasting conditions (temperature, roasting atmosphere and roasting time).. In pressure oxidation, the …

Roasting is a process of heating a sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth …

Study on Mineral Separation

A new mineral processing and metallurgy technology was proposed, which was that the ferro-nickel concentrate was prepared from laterite ore by coal-based direct reduction. Under the reduction of cheap reductant and the catalysis of composite additives, the effects of coal-based direct reduction were enhanced and the ferro-nickel was extracted.
