Abstract

The invention discloses a zinc oxide mineral beneficiation collecting agent and a preparation method of the zinc oxide mineral beneficiation collecting agent, in particular to a metal zinc oxide mineral beneficiation collecting agent and a preparation method of the metal zinc oxide mineral beneficiation collecting agent. The zinc oxide mineral beneficiation collecting agent comprises, by weight, 18%-25% of dodecanamine, 25%-30% of cetylamine, 38%-45% of octadecylamine and 4%-7% of active agent. The zinc oxide mineral beneficiation collecting agent is relatively resistant to low temperature and can be used without heating ore pulp, when the zinc oxide mineral beneficiation collecting agent is used under the condition that the temperature of the ore pulp is 15-25 degrees, compared with an original collecting agent, the zinc oxide mineral beneficiation collecting agent has the advantages that the obtained concentrate indexes are that the concentrate grade can be improved by 1.7%, the recovery rate can be improved by 5.76%, and the beneficiation cost can be greatly reduced. The zinc oxide mineral beneficiation collecting agent particularly has wide adaptation to high mud deep oxidation zinc oxide raw ore.

Description

technical field [0001] The invention relates to a zinc oxide mineral dressing collector and a preparation method thereof, and relates to a collector for metal zinc oxide mineral dressing and a preparation method thereof. Background technique [0002] There are many kinds of minerals contained in zinc oxide ore, the ore structure is complex, and the associated components are very unstable. The ore contains high clay, iron oxide minerals, soluble salts and other gangues and other reasons, and contains a large amount of clay and limonite. The flotation index of zinc oxide ore in my country is still low due to the high content of soluble salts and other reasons. [0003] At present, the flotation of zinc oxide ore mainly uses a single primary amine as a collector. With the change of ore properties, a single collector can no longer obtain ideal flotation indicators. The composite collector has a synergistic effect in the flotation process and can effectively improve the concentra...
