flotation process step by step description in mining


flotation optimization scheelite


Flotation process, named as froth flotation process, is based on difference of surface of various minerals, by means of buoyancy of the bubbles from the slurry, to sort minerals. Its main process is that the bubble with selective slurry with incompact adhere on the liquid interface rise, then scrape foam formed on the surface of pulp. Read More

The Mining Process – Waihi Gold


The Mining Process. The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
