Abstract

The invention discloses a method for designing flotation reagent molecules based on fragments. With the help of a computer auxiliary molecule design technique, molecular mechanics and quantum chemistry calculation, the active fragments which are small in molecular weight and high in relative combination efficiency are obtained by sieving through detection, then flotation reagent molecular structures high in activity are obtained after the methods of producing, splicing and fusing are utilized for optimizing the active fragments, and the flotation reagent molecules are obtained through the steps that a fragment molecular compound library is established, active fragment molecules are sieved, and lead compounds are sieved. The dual advantages of high efficiency of the computer auxiliary molecule design technique and the flexibility of a molecule assembly technology are combined; the inspection range for the molecules is scaled to the inspection range for the molecular fragments, in this way, the success rate of reagent formulation is greatly increased for the reagent molecules, the designing efficiency is effectively promoted for the flotation reagent molecules, and the new method isfurther provided for designing flotation reagent.

Description

technical field [0001] The invention relates to a molecular design technology of a flotation agent, in particular to a fragment-based molecular design method of a flotation agent. Background technique [0002] At present, the overall endowment of mineral resources is getting worse and worse, and the problems of poverty, fineness, and miscellaneousness are becoming more and more prominent. They are deeply buried, low-grade, and most of them are associated ores, making extraction difficult. The research and development of high-efficiency, low-toxicity, and low-pollution dressing and smelting agents is the key to the efficient separation, extraction, and comprehensive development and utilization of complex mineral resources. The traditional flotation agents can no longer meet the requirements, and the demand for efficient and green separation and smelting agents is very urgent. Molecular design and screening of new flotation reagents is a major trend in the development of mine...
