Laterite nickel ore resources are surface crustal deposits formed by Fenghua-Linfiltration-Sediment of nickel sulfide ore rock masses. They mainly contain nickel, iron, magnesium, calcium, manganese and other metals. As the resources available for development of nickel sulfide are significantly reduced,…

The lithium content in the earth’s crust is relatively low, and salt lakes have become a rich source of lithium resources. Lithium is widely used in many fields such as military, aerospace and glass manufacturing due to its excellent physical…

At present, the commonly used methods for treating zinc-containing pickling waste generated in the hot-dip galvanizing industry include neutralization and precipitation, acid distillation method, flotation method, ferrite method, ion exchange method, microbial method, membrane separation method, electrodeionization technology, etc. Considering…

Nickel and cobalt are widely used in the electronic field. With the development of industry, the market prospects of nickel and cobalt are huge. Because the physical and chemical properties of nickel and cobalt are very similar, it is difficult…

N,N-dimethylacetamide (DMAC) is widely used as chemical raw materials and organic solvents in petroleum, chemical, pharmaceutical, pesticide and other industries. It has strong polarity, chemical stability and biological toxicity. Dimethylacetamide (DMAC) is an important pharmaceutical raw material and is widely…

In the fine chemical synthesis process, the extraction and washing (including water washing and alkali washing) processes are essential links. Their main purpose is to remove solvents and by-product salts from the reaction solution. However, at present, these two processes…
