A kind of quartz mineral purification flotation agent

Abstract

The invention relates to a quartz mineral purification flotation agent. The quartz mineral purification flotation agent comprises, by percentage, 20% to 30% of mixed amine, 30% to 40% of petroleum sodium sulfonate, 5% to 10% of hydroximic acid and 30% to 40% of industrial alcohol; and in each ton of quartz sand, 0.5 kg to 1.5 kg of flotation agent is contained. The quartz mineral purification flotation agent has the beneficial effects that a floating agent mixture is stable in property, selectivity is good, the impurity removal effect is obviously superior to that of products of the same type, water solubility is good, environment temperature adaptation is high, mixing and mutual dissolution in any proportion to water can be achieved at the environment temperature, the adaptation of a reagent is wide, the good impurity removal purification effect is achieved, the purification efficiency is high, the use amount is small, in each ton of quartz sand, the use number of purification flotation agent ranges from 0.5 kg to 1.5 kg, the mineral separation cost is greatly reduced, no pungent smell exists, the work environment quality of production operators is obviously improved, and the use number of flotation agents is small.

Description

technical field [0001] The invention relates to the technical field of non-metallic ore purification and processing, in particular to a flotation agent for purification of quartz minerals. Background technique [0002] With the development of the country's low-carbon environmental protection economy, the development and utilization of clean energy represented by solar energy is becoming the focus of current work, forcing quartz sand as a basic material for solar energy development and utilization to receive more and more attention. Quartz sand is a kind of quartz particles processed by crushing quartz stone. It is a hard, wear-resistant and chemically stable non-metallic silicate mineral. Its main mineral component is SiO 2 , the color of quartz sand is milky white, or colorless and translucent, Mohs hardness is 7, quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelti...

Problems solved by technology

Quartz sand purification generally includes grinding, scrubbing, gravity separation, magnetic separation, flotation and chemical treatment. Usually, muddy impurities are removed by scrubbing, heavy minerals are separated by gravity separation, and magnetic minerals are removed by magnetic separation. For impurity minerals such as feldspar, cuttings, pyrite and pyroxene, which are similar in density to quartz and have weak magnetic properties, they need to be removed by flotation. Therefore, an efficient flotation agent for quartz sand purification is urgently needed at this stage. , after extensive searching, no ideal technical solution has been found
