The main factors affecting floatation include grinding fineness, pulp concentration, dosage of medicament, amount of aeration and flotation time.Usually, these process conditions need to be determined by mineral processing test and practical experience. The floatation process is usually used in the flotation of gold ore, and the stage grinding process is adopted for the ore with uneven grain size. China generally adopts a grinding-floating process to achieve the enrichment of useful minerals.
Requirements for grinding fineness of gold deposits
The requirements for the fineness of the gold ore are generally required for the dissolution of gold wrapped in sulphide minerals, but the fineness of the grinding fineness of gold associated with the gangue requires a single dissolution of gold. At the same time, the fineness of a certain mineral is determined by experiment.
Mineral slurry concentration requirements for gold flotation
The principle of gold flotation is that heavy mineral slurry is used for flotation of large density and coarse-grained minerals. Conversely, when the flotation of small density, fine grain size and mineral slurry is thiner pulp, thicker pulp can be used to obtain higher recovery rate, and the thinner concentration is used to improve the quality of the concentrate.
Technical requirements for the selection of medicament
The flotation reagents, such as collector, activator, and foaming agent, are used in the flotation process of gold deposits. The collector is used to promote the floating of gold. The activator is used to increase the floating speed of gold. The foaming agent is used to increase the number of floatation bubbles.
