Froth flotation processes are carried out in flotation cells that are grouped into banks, and these banks are interconnected, forming a flotation circuit. A literature review shows the existence of papers related to flotation circuit design based on mathematical programming. However, due to the complexity of solving the mathematical model in most of the work, it is …

The effects of flotation parameters including pulp density, collector dosage, frother dosage, and dispersant dosage were statistically examined to obtain an effective approach for concentrating copper minerals. The sample ore used in this study was mainly flotation wastes that have been stored for more than 30 years and comprised mixed sulfide ...
Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. ... Laboratory column testing was performed on a Philippines Cu/Au ore to determine column amenability as either a rougher ...
