Is the flotation processing ineffective? Have you taken these eight factors into consideration?

In the process of flotation by flotation machine, there are many factors affecting the flotation effect, including iradjustable factors and adjustable factors. Non-adjustable factors refer to the nature of ore. Adjustable factors include grinding fineness, pulp concentration, pulp acidity and alkalinity, reagent system (prescription), pulp temperature, water quality, flotation time, etc. Do you know how these factors affect the flotation process? 1. Ore properties
Ore properties mainly include chemical composition, mineral composition, structure and structure, occurrence state of useful and harmful elements, physical and chemical properties of ore, etc. The fluctuation of raw ore grade will increase the difficulty of controlling flotation process conditions. Among them, the oxidation rate of ore has a great influence on flotation, mainly as follows:
A. The oxidation of metal minerals and gangue minerals will change the original mineral and ore structure, forming a series of soil or clay …

China quartz sand resources, production, price, application market and policy situation multidimensional analysis!

Glass raw material quartz sand, so amazing!

Let's get to know silica sand today. With the rapid development of traditional glass industry, quartz sand is generally used to make flat glass, float glass, glass products (glass can, glass bottle, glass tube, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth and special anti ray glass. Especially with the development of global economy, the standard of building standardized management and the improvement of technology level of glass industry, all kinds of glass will be brilliant in the future construction.
Quartz glass has low coefficient of thermal expansion, high temperature resistance, good chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best UV spectrum performance, visible and near-infrared spectrum performance, and has higher mechanical properties than ordinary glass. Quartz sand is an important raw material of quartz glass. With the increasing demand of glass industry, quartz sand product…

Great use of quartz sand powder!

quartz sand powder for coating and painting
High purity quartz sand powder has special optical properties that conventional SiO2 does not have. It has strong ultraviolet absorption and infrared reflection characteristics. The addition of silica powder to the coating can form a shielding effect on the coating, achieve the purpose of anti ultraviolet aging and thermal aging, and increase the thermal insulation of the coating. The hardness and adhesion of the UV curable coating are improved and the absorption of UV radiation is weakened by doping high-purity silicon powder into the UV curable coating. Thus, the curing speed of UV curable coating is reduced. High purity silica powder has a large specific surface area, shows great activity, and can form a network structure when the coating is dry. At the same time, the strength and finish of the coating are increased, the suspension of the pigment is improved, and the color of the coating can be kept unchanged for a long time. The amount of…

In 2018, the market scale of China's quartz sand exceeded US $3 billion, and the demand for high-purity quartz sand grew rapidly

Quartz sand is an important industrial mineral raw material, non chemical dangerous goods, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries. In the market, silica sand is the most basic quartz mineral product, which can be divided into quartz sand, quartz powder, ultra-fine silica powder, cristobalite, high-purity quartz, etc. according to the different grade and processing degree of the ore body itself. Quartz sand mainly refers to river sand, sea sand and weathered sand with more silicon dioxide. In addition to the main component silicon dioxide, it also contains iron oxide, clay, mica and organic impurities. It is mainly used as raw material of glass industry and ceramic industry, and flux of metallurgical industry. Fine quartz sand can be used as abrasive for grinding glass, etc. The main products of quartz sand include ordinary quartz sand, refine…
