At a copper mine near Tucson, Arizona, the concentrator can process up to 100,000 tons of sulfide ore a day. The mine had previously relied on pneumatic actuators to control the pulp height in its flotation cells via modulating dart valves. These actuators lacked precision due to the compressibility of air.
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. Froth flotation [ edit ] Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario.
This means that 4.3% of the copper present in the ore was lost in the tailings. (d) The % Weight Recovery is equal to the % Weight of the concentrate in Table 1. It can also be calculated from the assay values given in the table, as follows % Weight Recovery = 100183;(2.09 0.1)(20 0.1) = 10%

1. Flotation process are widely used for copper extraction. The ore pulp slurry is pumped to flotation cells for extracting. The flotation cells are divided into several parts roughing, concentration and scavenging (the exact numbers of stages for each part should be decided by test work to reach the best recovery), and with the use of frothing agent and collecting agent, the copper concentrate will be collected.
RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., Department of Mining Engineering Supervisor Prof. Dr. Mustafa 220;mit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching.
Flotation of Copper Ores. The concentrate can then be reground and refloated with the production of a high grade copper concentrate together with a low grade pyritic tailing suitable for return to the roughing circuit. This method is likely to be less costly than one involving the fine grinding of the whole ore.
The crushed copper ore (containing, for example, 0.75% Cu and 0.015% Mo) is fed to the grinding circuit where water is added and the ore is ground to the proper size. Lime and an oil for collecting molybdenum are usually added in the grinding circuit. A copper collector may also be added at this point. The pulp progresses to the flotation cells.
COLUMN FLOTATION TECHNOLOGY IMPROVES MINERAL PRODUCTION. Column flotation cells were introduced to the market place about thirty ago years as devices capable of producing concentrates that were lower in impurities than those produced by other types of flotation machines. The ability to operate columns with deep froth beds and to wash
High grade hematite ore is crushed and classified into three main product categories; lump ore, pellet ore and sinter feed. Until about five years ago, the fine iron was routinely discarded. flotation cells to column flotation cells over a period of 2 years as part of a program to reduce plant operating costs.

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.
The ore is mined from an open pit, crushed and fed to ten ball mills. The concentrator is divided into two parallel comminution flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage.
