New collection agent for cassiterite flotation
Although there are many kinds of existing collectors , there are still some problems, such as high cost, polluted environment, and difficult processing of fine-grained grades. Therefore, many new collectors have been developed at home and abroad in recent years, such as ZJ-3, BY. -9, CF, SR, etc. Metal Casting Parts,Functional Hydraulics Parts,High-Tech 3D Printing Provider,Metal Machining Parts Guangdong Fenghua Zhuoli Technology Co., Ltd , https://www.fhzl3d-printer.com
ZJ-3 is a successful new collector for Zhu Yimin and other research constitutions. The agent is highly toxic and low-toxic, and is suitable for treating fine-grained cassiterite having a degree of less than 19 μm. ZJ-3, auxiliary collector TBP and inhibitor CMC were selected by Chehe Plant for a coarse, two-precision and one-sweep flotation. The grades were selected from the ore with a mass fraction of 1.16%, and the grades were recovered by l8, 29%. Rate 92. 68% tin concentrate.
BY-9 cassiterite chelating collector, any economic groceries, etc., is recovered by flotation tailings tin sulfide ore more gold from cassiterite. By comparing the flotation effects of BY-9, C9 hydroxamic acid and Sun 2#, BY-9 has the best collection effect, and the dosage is 1000g/t. An effective promoter P86 for collecting 100 g/t of cassiterite and 50-5 g/t inhibitor BY-5 and 50 g/t2# oil were added to finally obtain a concentrate having a grade of 48.76% and a recovery rate of 49.88%. The floatability of cassiterite and silicate is equivalent. When Mengzi Mining & Metallurgy Co., Ltd. handles tailings, BY-9 is used as collector, P86 is auxiliary collector, sodium carbonate and BY-5 are inhibitors ( The main component is the essence), and a tin concentrate with a tin grade of 53.58% and a recovery rate of 50.12% is obtained.
CF is a new type of chelating collector developed by Beijing Research Institute of Mining and Metallurgy. It is suitable for flotation of cassiterite and strontium minerals. It has strong ability to capture cassiterite and has good selectivity, and has good application prospects.
SR is a new type of high-efficiency collector for fine-grained cassiterite. For the ore of No. 100 (105) ore body, the agent is used to assist the collector P86, which can achieve the concentrate grade and operation recovery rate of 11.43 respectively. % and 88.72%.
