    Separating Minerals By Floatation

    a high ph is important in the processing of copper ore to maximize this mineral‘s floatation properties. most copper ore slurries tend to be acidic. plants typically add lime to the slurry in the mill or floatation circuit, increasing its alkalinity. a typical copper operation contains many floatation cells, often with a ph sensor in each cell.,innovations in copper mineral processing technology,• heavy medium separation is the process of separating copper ores by a specific medium (ferro-silicon) density. • testwork on copper ores at a size range of -76 mm+ 6 mm and a medium density of 2.8 demonstrated that 49% of the mass can be rejected whilst only losing 14% of copper
