Copper Flotation - Elmhurst College
The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of stone mills) to make bubbles, an alcohol to strengthen the bubbles, and a ...
60 Centuries of Copper: The Flotation Process
The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of …
Copper Sulfide Flotation - Mineral Processing & Metallurgy
Copper Sulfide Flotation Circuit. The pulp from the Conditioner is treated in a 10-cell “Sub-A” Flotation Machine and a 4-cell “Sub-A” Flotation machine. Sometimes conditioners are not provided; however, their use insures that reagents are thoroughly mixed into the pulp ahead of flotation.

(PDF) A Review of the Flotation of Copper Minerals
The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance ...
Lower-pH Copper Flotation Reagent System | Department of ...
A new reagent system, developed by Versitech, Inc., with assistance from DOEs Inventions and Innovation Program, recovers copper minerals at a much lower pH than conventional reagents and avoids floating pyrite. The process reduces or even eliminates both the lime used in copper flotation and the accompanying carbon dioxide.
Copper extraction - Wikipedia
Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.
Copper Mining and Processing: Processing of Copper Ores ...
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Sep 12, 2012 · This shows you the froth produced by flotation on a porphyry copper ore of about 1.5% Cu. You see the rougher flotation, the cleaner and scavenger circuit. It is a very small pilot plant small ...
Recovery of pyrite from copper tailings by flotation ...
1. Introduction. The concentration of sulfide copper minerals by means of flotation generates large volumes of tailings. It is estimated that one hundred twenty-five tons of tailings are generated per one ton of produced copper, and its generation is on a continuous rise because of the decrease of the copper grades .On the one hand, the tailing is considered an environmental problem as a ...

In the flotation tests, potassium dichromate (K 2 Cr 2 O 7), sodium diethyldithiocarbamate (DDTC) and methyl isobutyl carbinol (MIBC) were separately used as the lead depressant, the copper collector and frother.All reagents for tests are analytical grade. Tap water was used for the lab flotation tests. The stone analysis results of the tap water are shown in Table 4.
