Optical Spectrum Based Estimation of Grades in Mineral Flotation .

It is shown that the grades of the zinc flotation circuit concentrate can be estimated with a linear multiregression model using the measured froth spectra as input values. The model is then applied to estimate the grades of the concentrate between the originally sparse X ray fluorescence measurements. Additionally, some.

The Ore Grade and Depth Influence on Copper Energy Inputs .

Energy costs for copper mines with leaching operations were not found to be significantly affected by ore grades nor mine depth as all tested equations were rejected in the analysis. In case of mines with milling/flotation operations, a significant relation was established (p < 0.000, R 2 = 0.63 for surface mines and R 2 = 0.84.

Flotation: Advantage Circular Cells Mining Technology

Jan 13, 2012 . "This reflects important differences in flotation machine characteristics between the two processes. Grinding circuits are built and designed with fixed total mill volumes and energy input, so the grinding intensity is not a controllable variable, instead grinding retention time is changed by variation of feed rates.

Mine to metal: a practical balance for a large platinum producer

the ore fed to a flotation plant comes from multiple sources each source has to be sampled separately. So, relying on the grades determined using the sampling of concentrator input with cross stream slurry samplers is not an option for determining the grade from an individual shaft. Impala has developed a system for.

A Novel Mineral Flotation Process Using Thiobacillus ferrooxidans

Oxidative leaching of metals by Thiobacillus ferrooxidans has proven useful in mineral processing. Here, we report on a new use for T. ferrooxidans, in which bacterial adhesion is used to remove pyrite from mixtures of sulfide minerals during flotation. Under control conditions, the floatabilities of five sulfide minerals tested.
