Application Xinhai froth flotation process can be widely used in non ferrous metal, ferrous metal and nonmetal minerals, especially used in roughing and scavenging of large and medium sized flotation plant.It can process non ferrous metals, such as gold, silver, copper, iron, tungsten, lead, zinc, tin, molybdenum, nickel, tantalum, niobium and manganese ore and also process nonmetal minerals.
In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.
Jan 16, 2018 Fig. 1 shows the rougher flotation in a certain copper flotation site. During the whole flotation process, rougher is the first step of screening after ore is ground, mixed with water and classified. The products from rougher include the rougher froth on top of the cell and the pulp flow at the bottom of the cell.
An improvement in the froth flotation separation of metallic sulfide mineral ores, particularly those ores bearing copper and molybdenum, in which a mercaptan collector is used in an earlier primary flotation stage, the improvement comprising the addition of activated carbon to achieve deactivation of the mercaptan collector prior to the component mineral separation stage, thereby providing.
The froth flotation of ore and coal is significantly improved in recovery and grade of valuable minerals and coal when a depressant combination of an inorganic sulfite and the salts of certain sulfonated compounds are employed.
