a) concentration of the ore b) conversion of the sulfides and other copper compounds to copper c) purification of copper (a) Concentration of the ore. The ore is enriched by froth flotation (Figure 4). The powdered ore is mixed with oil and agitated with water in a large tank to which detergent has been added.
Copper Flotation Mineral Processing Metallurgy. The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation.
flotation performance (Shortridge et al. 1999; Dalvie et al. 2000). The objective of this research was to determine the level of copper sulphate dosage that can activate the chromite and also to evaluate the effect of the depressant type and dosage on the recovery of chromite in the flotation of UG2 ore. The
Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a facecentred cubic crystal structure, and ...
Feb 17, 2018· This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil. This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the wat...
Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.

Flotation or Heap Leaching? ... you can from there defined SX/EW copper concentration and flow, CCD flow rate, PLS (pregnant Leaching solution), ball mill and crushing capacity. ... Flotation of ...
May 11, 2014· b. Forth Floatation Process The finely powdered copper pyrite ore is introduced into water containing Rine oil. The suspension is vigorously agitated with air. The stony matter settles to the bottom and the ore is carried to the top in the forth. The object of this process is to increase the concentration of copper in the ore.
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.
1 Froth Flotation – Fundamental Principles ... This tells us that the concentrate has times the copper concentration of the feed. Grade/Recovery Curves While each of these single calculated values are useful for comparing flotation performance for
Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two decades of this century, whenopen pit mining, flo tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leachingsolvent extrac
The ratio of copper to Nickel (copper) copper concentrate increases with was to 16,03, reflecting increasing the selectivity of the process of copper flotation. Thus, investigated the reagent, which is a mixture of Tris(propanil)phosphine oxides, should be considered as an effective collector for flotation of sulfide copperNickel ore at ...
Copper production About 80 % of primary copper production comes from lowgrade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
