The invention discloses a selective
flocculation-column flotation
recovery method and
system of micro-fine particle
molybdenum cleaner
tailings. The method includes the following steps that: a dispersing agent and a collecting agent are added, so that first stirring and pulp conditioning is performed, and therefore,
mineral particles can be fully dispersed, and the surface hydrophobicity of target
mineral particles can be improved; a flocculating agent and a
foaming agent are added, so that second stirring and pulp conditioning is performed, and therefore, the target
mineral particles can be flocculated selectively; the cyclonic-static fine bubble floatatation column is utilized to perform
copper-
molybdenum mixed floating, and a roughing-concentration-
scavenging floatation process is adopted, and as a result,
copper-
molybdenum mixed floated concentrates and
tailings can be obtained; an inhibitor is added in the
copper-molybdenum mixed floated concentrates, so that third stirring and pulp conditioning is performed; and the cyclonic-static fine bubble floatatation column is utilized to perform copper-molybdenum separation, and a roughing-concentration floatation process is adopted, so that molybdenum concentrates and copper concentrates can be obtained. According to the selective
flocculation-column flotation
recovery method and
system of micro-fine particle molybdenum cleaner
tailings of the invention adopted, two kinds of micro-fine
particle separation ways, namely, selective
flocculation and column flotation, are adopted to recover molybdenum and copper in molybdenum concentrates and tailings, and therefore, the comprehensive
utilization rate of mineral resources can be improved, and the selective flocculation-column flotation
recovery method and
system have excellent
economic benefits and
social benefits.
