Flotation Reagent Introduction
Foam flotation beneficiation
1. Foam flotation is generally used to separate copper minerals and waste rock. We mix the factory’s copper paste with lime milk (water and ground limestone only) to provide a basic pH, and make pine oil (yes, it’s a by-product from the paper mill) into bubbles to enhance bubble alcohol and capture The chemical substance is called potassium amyl xanthate (or potassium dithiocarbonate).
2. Xanthate is usually added to the slurry in relatively small amounts. Xanthate is a long hydrocarbon (5-carbon) chain molecule. One end of the chain (ionic dithiocarbonate) is polar and attached to the sulfide minerals, while the other end is non-polar, where the hydrocarbon chain is hydrophobic-hydrophobic in water and is a non-polar hydrocarbon pine oil Molecular attraction.
3. Increasing the pH value will lead to more ionization at the polar ends and preferentially attach to chalcopyrite (CuFeS 2), while pyrite (FeS 2) exists alone. The air is blown into the storage tank and stirred like a giant mixer, creating foam. The chalcopyrite grains are covered with xanthate molecules, and their hydrophobic ends shake around, desperately trying to get out of the water.
4. They will stick to oily foam. When the bubbles rise to the surface and flow past the edge of the storage tank, they will be covered with chalcopyrite particles. Thus, through a series of steps, the copper ore is concentrated to a final copper content exceeding 28%. The waste stone particles will not adhere to the bubbles and fall to the bottom of the storage tank. The waste that comes out of the bottom of the storage tank at the end of this process is called "tail". It is nothing but ground rock from which copper minerals have been removed.
The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals. Once at the surface, the select minerals are supported by a froth layer until they are removed.
DESCRIPTION OF PROJECT: Objective: Operational experiments with flotation machines of different construction and with different flotation reagents. Examination of all available sedimentation accelerators and filtration aids. In the area of dewatering and washery-water clarification, the testing and modification of filter types, Dorr-type thickeners and Spitzkasten plant. The purpose of the tests is the provision of the necessary data for a fully automated system for the treatment of fines.
