The ores typically contain low percentages of copper and have to be concentrated before refining (, via froth flotation). Figure 1 : Chalcopyrite extracted from Zacatecas, Mexico. Image used with permission from Rob Lavinsky () under a license.
ABSTRACT 484 Characterizing flotation recovery variability of copper ores Cornelius F Vos* Deirdre J Bradshaw Julius Kruttschnitt Mineral Research Centre, Sustainable Minerals Institute, University of Queensland, Brisbane, Australia ABSTRACT The detailed understanding of the variability in process performance parameters within an ore body forms a key aspect of ensuring that proper decisions ...
The mixed collector ratio of SIBX: Armac C was varied as 0:1, 1:1, 1:2, 1:3, and 1:4. This investigation showed that using Armac C in conjunction with traditional SIBX collectors can successfully simultaneously recover copper oxides by flotation. The rougher scavenger copper recovery was as .
Copper oxide is more difficult to recover than copper sulfide. Presently, the three main treatment methods of copper oxide are flotation [2,3], leaching [4], and beneficiationmetallurgy combination processes [5]. The flotation method can be divided into the two following types: direct flotation and sulfidation–xanthate flotation.
2. (Nautical Terms) power or ability to float; buoyancy. 3. (Metallurgy) Also called: froth flotation a process to concentrate the valuable ore in lowgrade ores. The ore is ground to a powder, mixed with water containing surfaceactive chemicals, and vigorously aerated.
Flotation. Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.
Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (, via froth flotation). Figure 1: Chalcopyrite extracted from Zacatecas, Mexico.

The Flotation of Samples with Sulfurization of Oxidized Copper Ore. For the sulfurization process, two samples were prepared in two different autoclave mediums: Sample A containing H2S + g H2O for one kg of copper ore, and Sample B containing g H2S + g H2O for one kg of ore.
CopperMolybdenum ores. Flotation is conducted at high pH levels often times greater than 11 using lime to ensure good depression of sulphide minerals, particularly iron sulphides and copper. Other depressants used include cyanide and Nokes reagent (thiophosphorous or thioarsenic compounds). While there is primary molybdenum mine production,...
After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and "worthless" rock, called gangue (pronounced "gang"). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.
FLOTATION OF COPPER MINERALS FROM NORTH WAZIRISTAN COPPER ORE, ON PILOTSCALE M. Mansoor Khan, Mazhar Rafiq and *Ehteshamullah Khan (Received on and, in revised form, ) ABSTRACT Flotation process parameters were studied to concentrate the copper content Chalcopyrite of North Waziristan copperore on Pilotscale to obtain
The total and acid soluble copper assays of the tail from Test D were % and % Cu, respectively. This shows that the residual copper found in the tail was mainly associated with copper oxide minerals. The total copper, sulphide copper and oxide copper recoveries of %, % and %, respectively.
The flotation concentrate contained % Cu, % Pb, % Zn, % S, and % CaO; copper sulfide accounted for % of the copper, lead sulfide for % of the lead, and zinc sulfide for % of the zinc.
2. 2. Flotation Procedure All the flotation testwork was done using the Denver laboratory machine with a stainless steel flotation cell. The required mass of nickelcopper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about

Copper A Metal Used Through The Ages. Copper was one of the first metals ever extracted and used by humans, and it has made vital contributions to sustaining and improving society since the dawn of civilization. Copper was first used in coins and ornaments starting about 8000, and at about 5500, copper tools helped civilization emerge from the Stone Age.
