Abstract

The invention discloses a compound catching agent for beneficiation of micro-fine particle porphyry molybdenum ore. The compound catching agent comprises the following components in weight ratio: 1-5 percent of hydrocarbon oil, 0.001-1 percent of dithiophosphate matter, 0.001-1 percent of diltiazem matter and 100-200 percent of water. Moreover, the invention also discloses the application of the compound catching agent in the beneficiation of the micro-fine particle porphyry molybdenum ore. The compound catching agent disclosed by the invention is strong in collecting capacity and good in selectivity, in favor of the improvement of the concentrate grade and the recovery rate of molybdenum when being used for the beneficiation of the micro-fine particle porphyry molybdenum ore, and capable of effectively solving the problem that the use ratio of micro-fine particle porphyry molybdenum ore resources is low. Moreover, the dispersibility of the compound catching agent is good in water, so that the dosage of an agent is reduced, mineralization can be accelerated, the flotation time is shortened, and promotion and application are assisted.

Description

technical field [0001] The invention relates to the technical field of molybdenum-containing mineral processing, in particular to a composite collector for beneficiation of fine-grained porphyry type molybdenum ore and its application. Background technique [0002] my country is a country rich in molybdenum ore resources, and its reserves are second only to the United States, ranking second in the world. The molybdenum ore resources that have been used and planned to be used are mainly molybdenite. The main characteristics of my country’s molybdenum resources are: first, the types are mainly porphyry type, skarn type, vein type and sedimentary type, among which porphyry type is the main type, accounting for about 71% of the total reserves of molybdenum ore in the country; It is low-grade and mostly fine-grained deposits, accounting for about 65% of the total reserves. However, it is a consensus in the industry that fine-grained ore is difficult to separate. Whether it is sul...
