Tungsten Ore GY Chelating Collecting Agent

Tungsten ore component are complex in China, useful mineral grains are fine, low grade mineral is easy to beneficiate. In early period, tungsten concentrate and scheelite mixed ore is difficult to select. Thus caused a lot of waste in resource and increase cost. Economy efficiency is low. With newly development tungsten ore GY chelating collecting agent putting into use, it solves this issue.

GY chelating collecting agent is combination of benzohydroxamic acid and fatty acid agent, it has fine collecting property for both concentrate and scheelite. Therefore, tungsten concentrate and scheelite can be floated under mixed condition without separation. It can help some mine with low economy efficiency.

According to property of concentrate and scheelite, use GYB and GYR as collecting agent, lead nitride as active agent, sodium carbonate as adjusting agent of mineral slurry medium, sodium silicate as inhibitor of vein minerals, mixed flotation of them are realized. WO3 recovery rate is 86.64%.

GY chelating collecting agent solves the issue for mixed tungsten ore flotation, save some mines from bankruptcy. With the exhausting of tungsten concentrate, concentrate and scheelite mixed mine is the next option. There is no doubt that GY chelating collecting agent is essential for its beneficiation.
