Copper recovery methods from metallurgical waste

Typical processing flowsheet for metalliferous ores The flowsheet in Figure 1 shows diagrammatically the typical sequence of operations in the process plant. The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals.

This would allow the current use of rivering disposal to cease. Comparison of coal-rank terminologies by country. Pollutants become less bioavailable and livestock, wildlife, and human exposure is reduced. The molybdenum grade value corresponds to molybdenum disulfide molybdenite ; molybdenum recovery is at present In a description of tailings impoundments, however, the U.

In a gyratory crusher, a round moving crushing surface is located within a round hard shell which serves as the stationary surface figure 3.

Copper extraction

The molybdenum recovery plant has a capacity of 2, tons per day of copper-molybdenum concentrates. Abstract A complex process for the recovery of copper and zinc from mining and metallurgical wastes has been investigated and proposed.

Metallurgical Accounting Formulas | Concentration and Recovery in Mineral Processing

Examples of moving screens 4. Moreover, these methanogens change the structure of the tailings pond and help the pore water efflux to be reused for processing oil sands. Coal is a major source of energy in the production of electrical power using steam generation.

The crowding causes the bed to dilate allowing heavy minerals to migrate and move along the bottom, while lighter particles are forced to the top. Considerable work remains to be done. InLa Caridad finished a large exploration program of 50, meters. Vitrinites are derived primarily from cell walls and woody tissues.

Screening and Classification The size distribution of the particles must be controlled for a number of reasons at various stages of a mineral processing plant: The vibratory screen is probably the most common screening device found in mineral processing applications.

V Potter and around the same time by G. For example, recent advances using optical sorting methods is being employed in the diamond industry using an x-ray beam. The ratios of concentration, Kcu and Kzn are those for the copper and zinc concentrates, respectively, with Rcu and Rzn the percentage recoveries of the metals in their corresponding concentrates.

Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminum alloys. A solution called pickle liquor, which usually contains acid, is used to remove the surface is commonly used to descale or clean steel in various steelmaking processes.


Department of Civil Engineering, Jaypee University of Information Technology, Waknaghat, District. Mining news topics from The latest news on mining, mines and mineral properties, mining companies and metal prices. Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.
