Froth Flotation Circuit Design And Basic Testwork The rougher and scavenger concentrates may be reground to a predetermined liberation size and then subjected to two or three stages of cleaner flotation to produce a final flotation concentrate cleaner flotation tailings is an intermediate product and is recycled within the flotation circuit

Froth flotation Wikipedia

The rougher flotation step is often followed by a scavenger flotation step that is applied to the rougher tailings. The objective is to recover any of the target minerals that were not recovered during the initial roughing stage. This might be achieved by changing the flotation conditions to make them more rigorous than the initial roughing, or there might be some secondary grinding to provide further

Evaluating Copper Rougher-Scavenger Flotation Circuit

04/11/2015 The recovery of liberated grains of sphalerite into the rougher and scavenger concentrate increases linearly with flotation time. Overall 15% of the liberated grains of sphalerite are recovered in the combined rougher scavenger concentrate. Liberated pyrite and non-sulphide gangue minerals are efficiently rejected out the scavenger tail stream.

Pilot Mill Flotation of Serpentinized Platinum-Palladium

BENCH-SCALE FLOTATION TESTS ROUGHER FLOTATION Bench-scale tests were made to deter­ mine the amenability of serpentinized ore to flotation using conventional anionic collectors for sulfide minerals. During preliminary tests, no significant differ­ ence in rougher flotation results was ob­ tained between ores that were dry-ground

the rougher/scavenger flotation circuit consistently recovers 91% of the total copper sulphide minerals, with the greatest loss typically being from the >75µm and <7µm size fraction. the enrichment ratio on the rougher/scavenger flotation stage is around 4.5 to 5.0. the tailing from the rougher/scavenger flotation circuit is sent to the final

The effect of regrind mills on the separation of

01/11/2015 A laboratory rod mill and a laboratory stirred mill were used to regrind rougher flotation concentrates. It was found that chalcopyrite and pyrite exhibited different flotation behavior after regrinding with the rod mill and the stirred mill, resulting in different separability of chalcopyrite from pyrite. The mechanism underpinning this phenomenon was investigated by a range of techniques

Soon after, the Elmore proc­ ess could be found in mills in Australia, South Af­ rica, Canada, England, and Wales.10 Although all rhe Elmore process mills eventually failed, due to excessive amounts of oil that were used, 11 the process was found in limited usc in Australia as late as 1938. Other experiments in

Evaluating Copper Rougher-Scavenger Flotation Circuit

A modal examination of the products produced by the copper flotation rougher-scavenger circuit reveal important information regarding the limits to the efficiency of the process, imposed by mineralogy, fragmentation and flotation capacity. Let’s discusses various aspects of rougher flotation circuit performance and how to evaluate its results .

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 5-15 weight percent of the ore feed, (directly related to ore grade).
