Studies of the Mechanism of Rock Mineral Flotation at Clarabelle Mill
ثبت نشده
چکیده
At the Clarabelle mill, significant amounts of rock minerals float inadvertently during nickel and copper sulfide flotation, causing poor concentrate grades. It is known that the rock minerals that report to the concentrates are amphiboles and phyllosilicates. However, the latter are found only on concentrates obtained by processing highly altered ores. The amphiboles, which occur as both primary and secondary minerals in the Sudbury basin ores are double-chain ionosilicates containing hydroxyl (-OH) groups. The chemical composition of amphiboles may be represented by a general formula [1]: A0-1B2C5T8O22(OH,F)2, where: A = Na or K, B = Ca, Mn, Fe, Mg, or Li, C = Mn, Fe, Mg, Fe, Al, or Ti, and T = Si or Al.

Modofication of the Sarcheshmeh copper complex flotation circuit in response to a reduction in feed grade
The new copper processing plant of the Sarcheshmeh copper complex consists of two parallel circuits. After a primary crushing, the ore is sent to a SAG mill, and the product is further ground in a ball mill. The overflow of the hydrocyclones is fed to a flotation circuit that contains 8 rougher tank cells (RCS130), 3 cleaner cells (RCS50), 5 scavenger cells (RCS50), and a flotation column (as r...

Many research studies have been conducted on the liberation of locked minerals using a crusher and comparing this device with the other devices. This paper reviews the liberation of middle coal by different methods of crushing force. In the Tabas coal washing plant, particles of 0.5-50 mm size are processed through the heavy media method (using 3 Tri-flo separators) and particles of 0-0.5 mm si...

Gold deposits are varied regarding their geological and geochemical settings. Hence,their processing methods must be best organized for achieving the desired recovery of preciousmetals. In this research, two types of hard-rock gold ores, each with specific characteristics fromKouh-zar region (south of Damghan city) were subjected to mineral processing tests at thelaboratory scale. The reference...
متن کاملFlotation of zinc silicate ore: A focus on effective parameters, synergistic effect of mixed cationic collectors and its mechanism
The present study addresses the direct flotation route for the concentration of a zinc silicate ore. Flotation of hemimorphite faces some challenges due to the similarity of hemimorphite and quartz surface properties. XRD, and XRF analyses, optical mineralogy and SEM with X-ray mapping were performed for characterization. The results showed that the quartz, hemimorphite, calcite and dolomite ar...
