Mechanical stirring type flotation device for gold concentrate

Abstract

The invention discloses a gold concentrate mechanical stirring type flotation device, and particularly relates to the technical field of gold concentrate flotation; the gold concentrate mechanical stirring type flotation device comprises a shell, wherein a driving mechanism is arranged at the top of the shell, and a screening net plate is fixedly arranged in an inner cavity of the shell; a raw material pretreatment mechanism is arranged at the top of the screening net plate in the inner cavity of the shell, a stirring mechanism is arranged at the top of the screening net plate, and a stock bin is fixedly arranged at the edge position of the top of the shell; the driving mechanism comprises a motor and a fixing plate, the motor is fixedly installed at the end, away from the stock bin, of the top of the shell, and the end of an output shaft of the motor penetrates through the fixing plate at the corresponding position and is fixedly sleeved with a gear. According to the device, intermittent discharging, repeated crushing, stirring flotation and other work can be completed at the same time only through one power source; therefore, the device is simple and efficient, crushing treatment of large materials can be achieved, and the problem that the flotation efficiency is reduced due to accumulation caused by the fact that the one-time discharging amount is too large can be solved.

Description

technical field [0001] The invention relates to the technical field of flotation of refined gold ore, and more specifically, the invention relates to a mechanically agitated flotation device for refined gold ore. Background technique [0002] The refractory gold concentrate obtained by oxidation of fine gold ore is leached with sodium hydroxide solution under the conditions of heating, pressure, and oxygen, so that the carrier sulfide and arsenic of the wrapped gold are oxidized, thereby releasing the wrapped gold. At the same time, sodium hydroxide oxidizes the intermediate product produced by sulfide, and leaching gold is transferred into the solution to form a gold-containing leaching solution. After cooling and filtering, the sponge gold is directly obtained by conventional metal replacement method. In the prior art, a mechanical agitation flotation device is generally used for flotation of fine gold ore. [0003] However, during the use of gold concentrate flotation de...

Problems solved by technology

[0003] However, during the use of gold concentrate flotation devices currently on the market, the materials to be treated are usually poured into the device, and the flotation agent is directly added for flotation. On the one hand, some larger materials cannot be fully flotation. , on the other hand, the accumulation of material is too much, resulting in the failure of some materials to contact with the flotation agent quickly, which reduces the flotation efficiency
