Bauxite ore flotation and desilication Production of alumina The new technology test is based on the content of the main minerals in the ore, and the lesser content of silicon-containing gangue minerals is floated out, leaving the concentrate in the flotation cell. Compared with positive flotation desilication technology, the advantages are: less flotation and more suppression, more rational technological principles; flotation of silicon-containing minerals can avoid collectors, etc. into the concentrate, thereby reducing or avoiding the accumulation of organic compounds in the Bayer process. Easy to remove silicon-containing minerals such as pyrophyllite and reduce the rate of crusting on preheated pipes; the concentrate has good dewatering performance and low moisture content.
Industrial trials have developed control of slurry dispersion and desliming techniques; establishment of structures and performance relationships for flotation agents that enhance the capture of aluminosilicate minerals and selective inhibition of diaspore; reveal major aluminosilicate minerals and cations Mechanisms of collectors in mineral interface interactions and flotation behaviors; Development of desilication efficient collectors, inhibitors, and foamers with low dosage, selective to silica minerals, and the establishment of a systemic antifloatation agent System and desiliconization process flow; control of selective and selective desliming; and the formation of a “bauxite selective desliming-cationic reverse flotation desilication†technology with China’s independent intellectual property rights, pioneering the reverse flotation of bauxite Desiliconization - Pipelined preheated dwelling to produce new alumina process.
The test results show that after the bauxite with a ratio of aluminum to silicon of 5.88, after reverse flotation, the aluminum-to-silica ratio of the concentrate is 10.12, and the alumina recovery rate is 82.40%. The concentrate is treated with the Bayer process, the pre-silicon removal rate reaches 43%, the dissolution of the concentrate, the red mud settling compression performance is good, the speed of the pipe crusting is low, and the alumina product quality is good.
The successful development of this new technology has enriched the principle of the utilization of low-grade diaspore-type bauxite resources in China.
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
