The Improvement of the Level of China's Iron Ore Beneficiation

Henan Hongxing Mining Machinery Co., Ltd.

Flotation is a kind of important mineral processing technology. In the world, Billion ore and materials be processed by using flotation separator every year.
It is used widely in various metal minerals and non-metal minerals processing.

In addition it can be used in chemical industry, agriculture, food, medicine, environment protection, etc.

There are a lot of factor can influence the result of ore flotation equipment. Such as ore property, mog, flotation consistency, flotation reagents addition, flotation cell level, flotation aeration rate, etc.

In addition ore property, mog, flotation consistency, flotation reagents addition are Controllable parameters.

The traditional manual control can’t make the parameters at their best. So achieving the flotation automatic control makes important sense.

In the first, the current situation of flotation control at home and aboard is introduced.

According to the situation of DAHONGSHAN copper mine, the flotation control system are consist of flotation tank level control system, flow rate control system, flotation reagents addition control system.

Flotation tank level control system can get an offset value by compare the detection level value with level setting value. Control the pneumatic actuator with offset value to make the flotation tank level at setting value.

Flow rate control system can get an offset value by compare the detection flow rate value with flow rate setting value.

Control the clampvalves with offset value to make the flow rate at setting value.

Flotation reagents addition control system The Mitsubishi PLC is used as controller, and use flow meter and concentration meter collection to get density and flow of ore.

In recent years, raising the level of China's iron ore beneficiation process is a new mineral processing equipment and the support of foreign advanced equipment, especially in recent years in the crushing, grinding and classification, sorting (including re-election, magnetic separation, flotation, etc.), dehydration, filtration and other aspects of the development or introduction of many new and efficient equipment, and has been successfully applied to provide device protection for beneficiation technology progress.
