REPROCESSING OF THE OLD FLOTATION TAILINGS

lished data [19], the average copper content in the processed ores varied from 4%, at the very beginning to 0.6% at the end of the Old Flotation Plant works. Copper content in the flotation tailings had been changing in the same period from 0.5% at the begin-ning to less than 0.1% at the flotation process ending, depending on the copper ore

RTB Bor, Serbia: Copper ore production up, processing

Jul 09, 2015· liming’s Vertimill VTM400 vertical grinding mill significantly enhances RTB Bor’s recovery of copper slag reprocessing. After 1,000 hours of operation, the VTM400 has doubled the slag recovery rate, especially important since it has a 1.6–1.8% copper content.

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

Copper Processing: The Quest for Efficiency at Scale E & MJ

In copper, as with many other commodities, as ore grades have fallen, orebodies have become more complex, with higher levels of impurities, some of which mines are penalized for at the smelting stage if left unchecked. “Arsenic is an example of an impurity that has increased in concentration.

Tailingsfo Dry Stacking of tailings

Oxidation of sulphides in the tailings can create high concentrations (but low volume) of seepage water. May not be practical for some ore types. Detailed geochemical testing is required. Dust generation is a common problem in arid climates and can occur relatively quickly after tailings disposal due to the low moisture content of the placed
