Recovery Of Copper From Oxide Copper Ore By :
flotation tests were unsuccessful in terms of both recovery and grade of concentrate product. the highest copper recovery of concentrate was found as 61.35% with 8.69% copper content. the concentrate with highest copper grade of 34.65% was obtained with only 26.98% copper recovery. unsuccessful flotation of the testflotation cells require the precise control of compressed air principle that the frothing speed setpoint controls the concentrate grade. for example: concentrate grade control If the concentrate grade is too low, then decrease the compressed air delivered to the fotation cell improves ore yields,flotation cell ore calculation.

Flotation Process Audit And Bottleneck Identification :
jun 14, 2017 instead of considering a bank of flotation cells as one black box, the feed, concentrate and tailings of each flotation cell can be sampled individually giving down-the-bank performance. this can be further used, for example, for froth surface area optimization based on the calculated froth carry rates or for air and level profiling down the circuit. the flotation model developed by the amira project, of which outotec is a sponsor, is regarded by industry as the most suitable flotation model to use for circuit optimisation. this model incorporates ore floatability with flotation cell pulp and froth parameters, residence time, entrainment and water recovery to the concentrate.properties. the samples generated during the batch flotation tests were analyzed for and chromite.4 ph, Eh and DO were measured in the flotation cell using 556 multi-probe system. the system was calibrated regularly. the measurement was made after the ore had been transferred to the flotation cell
