Flotation Circuit Regrinding

Closed Circuit Flotation with Regrinding Flowsheet

DESCRIPTION: Regrinding of scavenger flotation concentrate middling OR flotation cleaner tailing and refloating the ground product in closed circuit cleaning. ORE TREATED: Flotation middling containing valuable mineral particles attached to the gangue particles and which can be freed by finer grinding. ADVANTAGES: Middling is designated as such because it contains material which lowers the ...

Effect of Regrinding - Mineral Processing & Metallurgy

Although regrinding is important in this copper circuit, perhaps targeting other process streams for regrinding or a coarser regrind size should be considered in future testwork.

Effect of regrinding conditions on pyrite flotation in the ...

The grinding, rougher flotation, regrinding and cleaner flotation procedure was developed based on the pyrite flotation circuit at Telfer. The crushed pyrite (100 g) was combined with 150 g of de-ionized water, and ground in a stainless steel rod mill for 8.3 min using 4 …

Limits of the CIL circuit in copper–gold plants ...

However, regrinding can result in a significant proportion of the newly released copper ions which complex with cyanide, and therefore increases cyanide consumption by the CIL circuit. It is expected that regrinding the CIL feed followed by copper flotation may be an appropriate pre-treatment method for the CIL circuit after the copper ...

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone 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.

The development of regrind-flotation pre-treatment of the ...

At Telfer, the copper flotation tailings are pre-concentrated prior to CIL treatment via bulk flotation of a gold-bearing, pyrite concentrate. Thus, to implement the regrinding-flotation process prior to the CIL circuit, the prerequisite is to float the flotation stage

Pyrite-Gold Recovery in Copper Rougher Flotation Tailings

regrinding and aeration on the separation of pyrite from gold in copper rougher flotation tailings (0.07% Cu , 0.61g/t Au, tail grades). An aeration stage was applied both at the head of copper flotation (copper rougher feed) and after regrinding of the copper rougher tailings, before gold/pyrite selective flotation.
