'2018 world congress and golmud potash potash salt lake BBS' will be on August 21, 2018 - 24 in golmud in qinghai province. The organization form of the conference is to bring exhibition, exhibition will promote. Zhengzhou will join. cwl - source extraction M series new centrifugal extraction equipment appearance product equipment and technology exhibition, the exhibition number: T20, zhengzhou DE source extraction, we sincerely invite you to visit!

the meeting from golmud in Qinghai province people's government, the China inorganic Salt Industry association, Qinghai Salt Lake Industry Co. , ltd. jointly organized. And in 2015 successfully held '2015 world potash potash conference', on the basis of scientific plan for the construction of comprehensive utilization of salt lake resources and the industry comprehensive international conference once again. Except potassium resources in salt lake salt lake lithium and magnesium, and other elements can be carried out in the comprehensive utilization of resources, golmud is formed is given priority to with potassium, comprehensive utilization of salt lake resources and the whole industry chain.

although abundant salt lake lithium reserves in China, but unit of lithium content is low, magnesium lithium than on the high side, to a certain extent, has formed a technology and capacity constraints. At present, the domestic lithium salt lake to mention there are mainly five kinds of methods: precipitation, extraction, calcine leaching method, electrodialysis membrane separation technology, ion exchange method, the solvent extraction method is now the salt lake brine extracting lithium efficient green and low cost production process.

extracting lithium from salt lake brine system has a single extraction system and two kinds of synergistic extraction system. The extraction process with tributyl phosphate ester as extraction solvent, hydrochloric acid as extraction agent. Iron trichloride as the complexing agent, the multi-stage countercurrent extraction and reverse extraction, acid washing, such as phase, extraction liquid discharge, use empty return organic phase extraction stage. Get an extract of the finished product process of evaporation concentration, roasting, leaching, removing impurities, evaporation and concentration, soda ash precipitation and preparing lithium carbonate products.

the advantage of solvent extraction method is suitable for extracting lithium carbonate from than magnesia lithium salt lake brine, and the technology is feasible; But in the extraction process to deal with large amount of brine and bigger to the corrosion of the equipment, thus in the process of implementing higher requirements to the material equipment. So as the process of the high quality requirements, DE source extraction in previous extraction equipment is developed on the basis of. cwl new centrifugal extraction machine, the equipment used in chemical industry with strong corrosion resistance, compared with the traditional van and extraction tower equipment, under the effect of centrifugal force, the remaining time is short, split phase quickly, to adapt to the wide range of flow ratio, and processing power; By changing the weir plate and frequency control of motor speed can satisfy the different density and viscosity of liquid materials.

BBS, the conference will also set up five points from lithium lithium resources and materials in the BBS, BBS, metal magnesium and magnesium industry trace and new type fertilizer BBS, molten salt and energy storage industry BBS, boron industry and mirabilite alcali sulphide BBS etc. Detailed understanding of industry dynamics in the BBS.






DE source extraction to recommend DE source extraction invited to share 2018 world conference on potassium potash feast to help you understand extraction equipment and production capacity, technological process, characteristics of the equipment, such as detailed specification, at the same time can also see the relevant customer case and extraction equipment solution, the research trend, you can also browse all extraction equipment.
