Spiral Chute Pre-Graded Flotation of Low-Grade Wolframite And Scheelite Mixed Ore

Wolframite and scheelite ore in China is mainly a kind of tungsten ore mining in recent years, the strata are mainly quartz veinlet belt type and layered dip type tungsten deposit.

In the past, the main reason for the development of tungsten ore is the difficulty in the ore dressing process caused by the semi - symbiotic wolframite. The mineral composition, mineral characteristics and embedding relation of the ore are far more complex than the quartz vein type tungsten ore, and the mineral species are many, and are refractory ores. Raw ore tungsten, molybdenum grade is low, the majority of tungsten grade 0.1% to 0.3%, with an average grade of 0.233%, the average grade of associated molybdenum is 0.024%, therefore, to obtain qualified tungsten concentrate and molybdenum concentrate its more difficult.

In recent years, with the emergence of flotation technology and new collector, the floatation of wolframite and scheelite seems to be no longer difficult. Compared with the existing technology, grading the wolframite and scheelite ore can make the gravity separation or flotation equipment easier to separate useful ores and impurities from the corresponding diameter grade ores, reduce the loss of useful ores and improve the ore recovery rate. Therefore, this kind of wolframite and scheelite flotation collector can simultaneously floatate wolframite ore and scheelite ore.
