Flotation on the copper ore processing All details about

Foam Flotation for concentrate production from finely ground copper ore (0.5 Cu) Foam flotation is a process by which collectors condition a mixture of water (suspension) to make the copper minerals water repellent while leaving the non-Cu minerals hydrophilic.

Laboratory studies on a number of copper–gold ores 40 containing pyrite have shown that gold recovery in rougher–scavenger flotation is a function of pyrite recovery in the copper concentrate. Figure 12.20 shows the relationship between gold and pyrite recoveries using xanthate and dithiophosphate alone or in combination.

The concentrate with highest copper grade of 34.65 was obtained with only 26.98 copper recovery. Unsuccessful flotation of the test

Copper-Lead-Zinc ores

Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate. Whichever mineral constitutes the lower bulk concentrate mass will be floated away from the other mineral which is depressed for flotation selectivity reasons.

Figure 12.20 shows the relationship between gold and pyrite recoveries using xanthate and dithiophosphate alone or in combination.

Copper Concentrate Enrichment Process

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps. Some ores have associated problems such as chalcocite-coated pyrite and are difficult

lead concentrate flotation separator processing

Copper Lead Concentrate Separation. At the end the use of a sequential copper-lead-zinc flotation circuit produced the most efficient copper and lead separation. A bulk flotation process followed by a reverse flotation where copper was depressed and lead was floated from the bulk concentrate also produced separate concentrates but at lower

Flotation ore dressing Britannica

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. This article was most recently revised and updated by Chelsey Parrott-Sheffer Research Editor.

All the concentrate and tailings samples were analysed by ICP in order to make a metallurgical balance calculation. The industrial flotation circuit of Mineração Caraíba was designed for an ore type copper grade and feed rate different from those that are mined nowadays. This meant that the cells volume may not be optimised.

Copper-Cobalt oresDanafloat

Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small cyanide dosages. If the cobalt is found with chalcopyrite bulk flotation can be carried out with xanthate at pH 10 and separation made at pH 4 with an amine and

This tells us that the concentrate has 9.57 times the copper concentration of the feed. 1.1.1 Grade/Recovery Curves While each of these single calculated values are useful for comparing flotation

Copper ConcentratesCargo Handbookthe world s largest

The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24 up to 36 of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9 .

Under this scheme a bulk galena and sphalerite flotation concentrate is produced at pH 6.5 (modified with H2SO4) with some copper sulphate addition to ensure full sphalerite activation. The bulk concentrate is subsequently conditioned with sodium hydroxide to achieve an approximate 11.5 pH and collector addition from which a lead concentrate
