Copper Tailing an overview ScienceDirect Topics

The properties of copper tailings, a fine-grained residue waste produced from beneficiation of copper ore, and their effects on the properties of bituminous mix were studied by Oluwasola et al. (2014, 2015). The copper tailings were used at 20% content as a fine granite replacement for

Tailings Resolution Copper

Tailings. The mining process involves separating the copper ore from noneconomic rock. After removal of the copper, what remains is called 'tailings.' Tailings include particles of rock, water, and residual process chemicals. We will pump the slurry-like tailings via a pipeline to a designated facility for permanent storage.

According to research by mineral processing firm TON, the quantity of tailings generated each year by the copper industry alone amounts to 2.9 billion tonnes, and iron-ore production adds a further 1.6 billion tonnes.

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

Economic Potential for reprocessing Copper Mine Tailings

Four copper mine tailings in Chile were investigated for their elemental and mineral composition, in order to evaluate the potential for economic reprocessing. The sample material, taken for processing had Cu-contents between 0.1 and 0.5 %. Copper was abundant in various primary (mostly chalcopyrite) and secondary (cuprite, atacamite, b

Silica levels, which range from 14% to 20% in the barren ore, have reduced to 6.4% after processing; while alumina levels, which range from 5.9% to 8.8%, have reduced to 2.8% after processing. The iron ore wash plant also removes clays from the feed material, with the combined effect

Effect of Manganese on Silver Leaching

In Mexico and elsewhere there are large bodies of valuable silver ore containing manganese which present great, and hitherto insuperable, obstacles to a satisfactory extraction by cyanide. The proportion of the silver that is soluble in cyanide varies greatly and may be as low as 5% only. The mere presence of manganese in the ore is not invariably accompanied by refractoriness of the silver

Dual Leaching Method for Recovering Silver and Manganese

Less than 10 pct of the silver was extracted when minus 2.5-plus 1.3-cm ore pieces were leached directly with cyanide. However, extractions of 25 to 82 pct of the silver and 65 to 96 pet of the manganese were attained in laboratory column-leach tests using the dual leaching method on equivalent-sized ore pieces from

Extraction of valuable metals from manganese–silver ore

May 01, 2012 1. Introduction. Manganese–silver ore, which has been found mainly in South-eastern U.S, Latin America (Presic and Wey, 1986) and China (Jiang, 1996), has attracted great attention for its importance as a mineral resource, not only for manganese, but also for silver.In recent years, many efforts have been made to develop efficient and economical process to recover manganese and silver

Extraction of valuable metals from manganese–silver ore

A combined novel process was developed to extract valuable metals from manganese–silver ore. The preferential dissolution of manganese from the primary materials was achieved through reductive leaching in dilute sulfuric acid medium with sodium sulfite as the reductant.
