Control method of diatomite ore scrubbing process

Abstract

The invention discloses a control method of a diatomite ore scrubbing process and belongs to the technical field of mineral separation process control. The control method is characterized by including feeding quantity control, scrubbing density control, pH adjusting agent dosage control, scrubbing strength control, dispersing agent dosage control, sequence control and a controller. The method includes determining feeding quantity according to diatom content of diatomite ores, adjusting a water compensation motor-driven valve according to the feeding quantity, controlling the scrubbing density to be 30%-40%, adjusting a pH adjusting agent metering pump to enable the pH value of ore pulp to be 9-10, changing working efficiency of a first-slot scrubbing motor, a second-slot scrubbing motor, a third-slot scrubbing motor and a fourth-slot scrubbing motor of a scrubbing machine to control scrubbing strength, adding proper dispersing agent according to the scrubbing density to enable clay minerals to be in the suspension dispersing state which is favorable for the following centrifugal sedimentation and separation. The control method enables clay removing rate of the diatomite ores to be high, obviously improves hole plugging, remarkably improves specific surface area, is not large in breakage rate increase, and is especially suitable for scrubbing of clay minerals.

Description

technical field [0001] The invention relates to the technical field of mineral processing technology control, in particular to a method for controlling the scrubbing process of diatomite ore. Background technique [0002] Diatomaceous earth is a natural nano-microporous and regular distribution, large specific surface area, small bulk density, the main component is amorphous SiO 2 The natural siliceous porous non-metallic minerals are widely used in the filtration of beer, beverages, drinking water, industrial oils, etc., as well as in the fields of sewage treatment, building materials, chemicals, agriculture, rubber and plastic fillers, paper fillers, etc., and are indispensable for many industries. Mineral functional mineral materials have broad application prospects. [0003] my country is a country with large reserves of diatomite, second only to the United States in the world, ranking second. However, most of the diatomite reserves in my country are low-grade resource...
