Concentrate Thickener Operation
Concentrate Thickener Operation. In mining, when flotation is finished with the ore, and a final concentrate has been produced, often, both products will go to a concentrate thickener before it is dried for shipping. This is a very important step so here we discuss Basic Concentrate Thickener Operation. For the mine to get its …
Froth flotation
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

C = F/K = F (f — t) / (c-t) = the weight of the concentrate. Recovery %. Represents the ratio of the weight of metal or mineral value recovered in the concentrate to of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available.

Production of cobalt from copper-cobalt ores on the African …
A specific cobalt flotation circuit is run at KCM's Nchanga concentrator. The ore from the Nchanga open pit contains pockets of ore with higher grades of cobalt, typically about 0.3% cobalt and 1.3% copper. This ore is processed in campaigns through the cobalt flotation circuit, which is illustrated schematically in Fig. 11. The concentrate ...
Where to Install a Gravity Concentrator in a Flotation Plant?
Transcript: Now let's have a look at gold recovery from flotation circuits. The most common installation is here in the primary milling circuit. And the best way to describe the benefit here – or what it's doing economically in the circuit – is, let's say you have a large gold particle. And just for example, let's say you're lucky ...
Improving coarse particle flotation using the
The typical drop off in recovery for coarse sulfide particles within industrial flotation plants is best illustrated by the size-by-size flotation data reported by Lynch et al. (1981) in the well-recognized "elephant curve" shown in Fig. 1.More recent size-by-size recovery data show little has changed in the past several decades to expand the …

This report is the fourth in a Bureau of Mines series describing the sodium fluoride-lignin sulfonate-fatty acid process of froth flotation separation of fluorspar from complex …
Comparison of liberation determinations by particle area
To simplify programming, image analyzers commonly measure either linear intercepts or the areas of particles and grains to determine liberation based on polished section mounts. However, the concentration of minerals by flotation is based on reagents that interact with the exposed surfaces of the minerals. Thus, it is often perceived that …
Selective gold flotation at Sonora Mining's Jamestown concentrator
This paper discusses the replacement of AEROFLOAT® 25 promoter by AERO® 5688 promoter at Sonora Mining Corp.'s California Mother Lode concentrator. Flotation concentrate is trucked 120 miles to a leach plant in Nevada, so the reduced mass resulting from higher gold grades and reduced talceous gangue and barren pyrite …

Flotation. Since 2019 Concentrator advanced from Wemco flotation cells to tank flotation cells. The final milled product at 80% passing 0.15 mm is fed to the Tankcells Flotation Plant (TFP) with capacity of 1 745 t/hr, which is a counter-current circuit, where the copper is concentrated into the overflow of the rougher, cleaner and re-cleaner ...
Simulating the Impact of Ore and Water Quality on Flotation …
Blending of different ore types in the concentrator feed contributes significantly to maintaining a high recovery of valuable minerals with required grades in the concentrate. It is feasible to develop an ore-blending scheme over the life of a mine already in the design phase of the plant. In addition to ore characteristics, water quality is known …
