High nickel matte selective leaching method
High Nickel-Molybdenum Selective Leaching
High Nickel-Molybdenum Selective Leaching is a process used to recover valuable metals from mineral ores. In this process, a solution containing the metal-bearing mineral is treated with an oxidizing agent, such as sodium chloride or potassium chloride, t......
Preparation of rhenium compounds
Abstract
This article focuses on the synthesis of rhenium compounds by means of organometallic chemistry and their applications in various fields. The most common approaches to synthesizing rhenium compounds are the Grignard reaction, the organometallic exchange reaction, and the reduction of rhe......
bio-charcoal
Biological charcoal is charcoal made from animal, vegetable organic products. It is produced by dry distillation and oxidation. It is also called animal charcoal, vegetable charcoal and active charcoal.
Biological charcoal has two main sources of raw materials, namely animal materials and plant m......
Carbonization of polyacrylonitrile
Carbonylation of Acrylonitrile
The carbonylation of acrylonitrile is an important industrial process used to produce adiponitrile, which is then used to synthesize nylon 66. The reaction between acrylonitrile and carbon monoxide is catalyzed by complexes of nickel or cobalt, and it has been stud......
Non-oxide refractories
Non-Oxidizing Refractory Materials
The term refractory describes a substance or material that has the ability to resist high temperatures as well as abrasion. This resistance makes refractory materials ideal for a variety of industrial applications where heat may be an issue. The majority of refr......
