Asynchronous flotation of scheelite and wolframite mixture ore new technology based on the differences of magnetism, floatability and flotation kinetics of wolframite and scheelite, proposed asynchronous flotation of scheelite and wolframite mixture ore.

 

Strong magnetic shunt scheelite and wolframite ore - respectively flotation selection;

Recovery of Priority floating scheelite - magnetic floating wolframite new technology create the conditions for the recovery of subsequent fluorite and cassiterite, which is another technological advancement that different from the "Shizhuyuan Method" core technology that mix wolframite and scheelite synchronous mix flotation - flotation and gravity separation process.

 

(1) New technology of synthesis of benzohydroxamic acid chelating collector: compound hydroxylamine hydrochloride directly in the main flow, improve oximation process online control technology to significantly improve the conversion rate and reduce costs;

(2) New technology of synthesis of nitrosophenylhydroxylamine chelating: synthesis in the water phase, cancel toluene extraction process, eliminate pollution, reduce costs;

(3) New technology of a new series of scheelite flotation development: compound by the mixed fatty acids, hydroxamic acids (soaps) and the specific emulsifier. Develop personalized new collectors for different kinds of scheelite ores, , having advantages of both fatty acid and chelating collector
