ence of primary slimes, proper control of communition circuits especially effective grinding circuit control may be effective in reducing the generation of secondary slimes. Effects of Slimes on Flotation The presence of slimes in flotation systems results in deleterious effects on recovery, selectivity and reagent consumption .
Flotation. Froth Flotation Services. Grinding Solutions offers a comprehensive range of froth flotation services. We specialise in integrating comminution, grinding chemistry and froth flotation to optimise the whole process and/or to better replie plant conditions.
circuit configuration with double screen trommel attached to the mill, five cone crushers for secondary (2 crushers) and tertiary (3 crushers) crushing stage and nine ball mills in closed circuit with classifying hydro cyclones. The cyclone overflow feeds the flotation stage with a grind size P80 of 100 microns.
Overall native copper recovery from the gravity circuit is in the order of 50%. This reduces the mill circulating load and reduces coarse native copper (>200 micron) reporting to the tertiary circuit and subsequently the flotation circuit and potentially to the flotation tails. In .
Model of a Water Balance for a Conventional Flotation Copper Circuit Facility ... the amount of water required to process copper sulfide ore through a conventional crushgrindflotationconcentrate circuit ranges from roughly metric tons (t) to about t of water to process 1 t of ore [Wels and Robertson, 2003, 2004; Misra and others, ...
regrinding in the copper and pyrite flotation circuits at Telfer gold mine was taken as a case study and four research areas were addressed with the objective of developing fundamental understanding to provide practical guidance for the plant operation. The four areas investigated are: 1.
· In 1990, the copper and zinc flotation circuit was streamlined by adding column flotation cells and reducing the recirculation load to improve zinc recovery. In 1992, a Knelson gravity concentrator was added to each grinding circuit to improve gold recovery.

Grinding circuit. The grinding circuit usually consists of a SAG or AG mill and one or two ball mills. Grinding is continuous and fully integrated with subsequent flotation operations. SAG or AG mills. The crushed products are ground in SAG or AG mills. The selfgrinding machine can grind ore without grinding media such as iron ball, or steel ...
Telfer is a gold/copper operation, currently operating one open pit mine and one underground mine. The ore processing plant consists of two parallel trains involving semiautogenous mill, ball mill and crusher (SABC) grinding, flotation and leaching. Due to receiving relatively high grade underground ore for over half of its total feed, Train 1 frequently experienced cleaning circuit ...
The Copper Concentrator has two parallel grinding lines, two roughing and scavenging flotation lines, and common cleaning, recleaning and retreatment sections. During the first six weeks of the installation phase, one of the two flotation lines was fed by the conventional grinding circuit and the other by the autogenous grinding circuit.
grinding circuit and flotation plant with 4 Mt/y design throughput capacity being fed from a Sub Level Cave (SLC) mining operation. The concentrator will produce approximately 65 kt/y of copper in concentrate along with gold and silver credits, with a relatively high .
Usually, the grinding circuit contains at least two interconnected mills with material classifiers ( cyclones) separating the fine material from the coarse (that then goes for regrinding). The process is energy intensive with power consumption of roughly 20 to 30 MW and feed throughputs of 2,500 to 3,000 t/hr. Process variables are mill loads, motor torque and power, plus pressures and ...
· Flotation. The flotation circuit at the Veovaca concentrator consists of a bulk flotation circuit, zinc flotation circuit, pyrite flotation circuit, and barite flotation circuit. Each circuit will be discussed in the following subsections. Bulk Flotation. The purpose of the bulk flotation stage will be to recover a lead/copper concentrate.
Most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage of flotation. The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 515 weight percent of the ore feed, (directly related to ore grade).

A process for the flotation of nickel and copper sulphide minerals from talcose bearing ores comprising wet grinding the ore to produce an alkaline pulp thereof in a suitable state of subdivision for flotation wherein at least one alkaline reagent present is soda ash or ammonium hydroxide and the pH is within the range of from about 8 to ; conditioning said pulp with a collecting agent of ...
Figure 1 shows the flotation circuit of the Sungun concentrator plant. The process consists of grinding circuit with their associated flotation circuits. The grinding circuit products with d 80 about 90 μm are transferred to the rougher conditioner tank and then enter 12 rougher flotation tank cells, which are grouped into 6 banks of 2 cells each.
