  • Float-sink method and apparatus to determine beneficiation prospects of minerals
    Patent number: 8833562
    Abstract: A method for separating particles of different specific gravity from a sized ore feed, wherein the ore can be coal, metallic, non-metallic and mineral ores. The method particles from the ore are sieved to obtain size fractions of different particle size ranges, after which a load of particles of a size fraction are placed in a container and fluidized by passing a fluid flow through the load of particles. By lowering the flow velocity of the fluid through the load the particles are deposited in the container in one or more layers depending on the specific gravity of each of the particles, after which the deposited particles are separated in portions of different specific gravity. The portions represent different ore content of the particles in each portion on basis of which the theoretical yield of the ore can be determined. The invention provides an apparatus to carry out the method.
