How to control the amount of flotation reagent?
Posted on

Flotation agents are a major factor in regulating the floatability of minerals. Insufficient dosage can not be adjusted, minerals are difficult to select; excessive dosage can also cause adverse effects, not only reduce concentrate quality, loss of selectivity, but also waste. In fact, only a small amount of collector can be added to the flotation to form a hydrophobic film on the surface of the mineral. The amount of the same inhibitor and activation of a certain mineral is also very small . Therefore, in actual use, special emphasis should be placed on " appropriate amount ". And " selective " .

For different ores, due to the different properties, the fluctuation of the dosage of the medicament is also very large. Even if they belong to the same type of ore, the specific conditions of the deposit are different, the useful minerals and the content of the gangue are different, and the dosage is not the same. The approximate range is: the amount of collector is 20 ～ 1500g /t . In general, the amount of xanthate collector is small, about a few tons per t mine. Ten grams Above 100 grams, the amount of fatty acid collector is larger, about several hundred grams to more than one kilogram per t mine; the amount of foaming agent is 20 ~ 2000g /t ; the amount of activator is 200 ~ 1000g /t ; the amount of inhibitor is 100 ~ 200g /t ; medium conditioner is 500 ~ 3000g /t . When selecting a specific ore, a narrower range of dosage should be selected based on the test results. In actual use, as long as the material composition of the ore remains unchanged, the amount of the agent should not be arbitrarily changed.
