Flotation of Nickel and NickelCopper Ores . In the treatment of coppernickel ores, two main methods are used, which include sequential coppernickel flotation, when the copper in the ore is much higher than the nickel, and a bulk coppernickel flotation method, followed by coppernickel separation using nickel depression and copper flotation
Lead/Zinc Ore. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit. The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors.

Copper Nickel Flotation To confirm the results of the batch testing and provide the cooperating company with a large sample of the cobalt nickel and copperlead concentrates for further experimentation, pilotplant flotation tests were made.
Copper flotation process Mining – separating minerals by flotation Measurement made easy — Introduction The flotation process can separate a required mineral such as copper, nickel, molybdenum or zinc from ore. Flotation can separate this mineral from waste materials or from another mineral. The process starts with crushed ore. A ball mill
Oct 25, 2014· A milling curve for the Palabora copper ore was first derived. The ball mill was turned so that it was facing vertically upward. The required number of steel balls was poured inside the mill and about kg of the sample was delivered into the mill. The .
The Nova concentrator consists of a differential flotation circuit whereby copper bearing mineral are selectively floated prior to nickel flotation. It is imperative that losses of copper to the nickel circuit, and vice versa, are minimised.
Copper Applications in Metallurgy of Copper Copper Alloys. Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water,...
The useful minerals of Jinchuan highgrade copper and nickel suphfide ores were mainly nickel and copper, whose grade were respectively % and %. The content of MgO and SiO2, main gangue components, reached %. The key to improve the separation indexes of flotation concentrate was to inhibit the gangue minerals effectively, therefore, the effects of different kinds of regulators on ...

title = "chlorination of copper and nickel sulfide concentrates.", abstract = "A chlorination process for treating metal sulfide flotation concentrates is described. The process involves low temperature chlorination combined with sulfur chloride conversion and selective oxidation to produce nonferrous metal chlorides, elemental sulfur, and ...
Sep 17, 2011· Until 1907 practically all the copper mined in the USA was from underground vein deposits, averaging % Cu, whereas flotation allowed the mining of porphyry deposits of only % grade. Nevertheless, the flotation of copper ores still presents challenges to the minerals engineer.
Sep 17, 2011· The challenges in copper flotation that we came across during testing may be grouped as internal, species, and associated ganuge. Still we have not fully understood and each case is unique. Every project/program is a learning curve for me.
A process for beneficiating a finely ground ore containing sulfide minerals of copper and nickel by selective flotation to produce a copper concentrate and a coppernickel concentrate comprises pulping the ore with water to form a slurry, conditioning the slurry with an aqueous solution of SO 2 (H 2 SO 3 ) equivalent to from about 2 to about pounds of SO 2 per ton of dry ore for a time sufficiently long to .
Flotation Practice in Nickel Sulde Deposits. Nickel sulRde minerals such as pentlandite can, in general, be separated from their gangue by Sotation using a thiol group of collectors like xanthates and alkyl dithiophosphates in the presence of variety of activators, depressants and dispersants.
Smelting and refining of massive sulphides begins with the flotation of ore, typically in the range of % nickel, to an acceptable concentrate grade of 10 to 20% nickel. Concentrate smelting produces a high grade nickel matte which is then refined hydrometallurgically. With the majority of

International Nickel (INCO) and Sherritt Gordon use a bulk Cu/Ni float pictured below, followed by selective flotation of the two elements into separate concentrates. Other Canadian producers leave separation to the smelters. Flotation of a Copper/Nickel Ore Containing Pyrrhotite is as follows:
Improve efficiency of flotation separation processes for a wide range of ores and minerals. AERO® promoters are used extensively for the flotation of a wide range of minerals including copper, gold, lead, zinc, nickel, iron and many others.
flotation is used after autogenous grinding to produce copper and nickel concentrates. The plant throughput is approximately 7 Mtpa (2015) and it produces around 17 kt copper and 9 kt nickel annually, as well as, cobalt, gold, and platinum as byproducts. Flotation process control is .
selective flotation of copper and nickel sulfides Strategic Metallurgy have demonstrated differential flotation techniques for Western Australian copper and nickel sulfide ores in saline water. Historically, selective flotation of copper from nickel sulfides has been achieved through pH modification; however, this method is rarely efficient, resulting in significant rejection of copper units to the nickel circuit.
Getting copper from chalcopyrite, CuFeS2 Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated by, for example, froth flotation before refining.
efficiencies of copper and nickel from flotation concentrates and mine tailing. Keywords Mine Tailing, Flotation, High Pressure Leaching, Copper, Nickel 1. Introduction Flotation is of interesting topic in recycling ions by using surficial reactors. Its efficiency is dependent on the hydrophobic and hydrophilic properties of min
Concentration. For sulfide ores, both secondary ( supergene) and primary ( hypogene ), froth flotation is used to physically separate ore from gangue. For special native copper bearing ore bodies or sections of ore bodies rich in supergene native copper, this mineral can be recovered by a simple gravity circuit .
