success of floatation in copper tailings

1 Froth Flotation

This means that 957% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 - 957 = 43% This means that 43% of the copper present in the ore was lost in the tailings.

Flotation Tailings Processing Copper

Copper tailings: if the copper with high heavy metals content, the separation will be easier and apply the process of flotation If there exist magnetite in the copper tailings, it will firstly using acid leaching to precipitate the copper, then use magnetic separation accordingly Chat Now.

Copper Sulfide Flotation

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.

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 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different.

In this work, dynamic froth stability is used for the first time to investigate the flotation behaviour of copper tailings Reprocessing of material from tailings dams is not only environmentally desirable, but also increasingly economically feasible as head grades can be high compared to new deposits.

Introduction to Mineral Processing

Chemicals referred to as depressants are added to the pulp to reduce the flotation of the copper minerals while allowing the molybdenum minerals to float The tailings from the molybdenum plant are the final copper concentrate (typically greater than 30% copper).

Tailings

Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an oreTailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining.

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.
