Copper Recovery Through Smelter Slag Flotation in Atacama, Chile
Abstract (es) Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, Recycling tailings thickener overflow • Recycling concentrate or intermediate thickener overflow • Recycling potential mine effluent water. Water is commonly recycled when it drains out of deposited tailings and collects in TSF collection ponds. Likewise, any collected seepage or drainage from a TSF is commonly returned to the plant.Reducing mine water requirements ScienceDirect

Beginners guide to thickeners TON
Beginners guide to thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive theLead thickening cycle Pb cleaner flotation concentrate; Pb thickener froth surface layer; Pb thickener underflow and Pb thickener overflow.

Copper Processing Multotec
The copper concentrate is first placed in the smelting furnace to be heated up to 1260 °C and converted into molten liquid. The heated liquid is poured into a slag-settling furnace. During this step a combination of matte,a mixture of copper, sulfur and iron, and slag,a dense, glassy material made of iron, silica, and other impurities, isThe diameter of the thickener can be reduced to 1 / 3-1 / 2 of that of the common thickener, and the floor area is only 1 / 9-1 / 4 of that of the common thickener. However, the processing capacity per unit area has increased dozens of times. It is a new type of high-efficiency thickener which is increasingly widely used.Thickener Mineral Processing

This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue.It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores. The basic ideas stressed in this moly flotation flowsheet The final lead and zinc concentrates are pumped by concentrate pumps to Thickeners for dewatering prior filtration. The thickener underflow at approximately 50% solids is pumped to a Disc Filter by means of a Diaphragm pump. The filter cakes pass to concentrate bins for storage.
