Separation of hazardous polyvinyl chloride from waste

Dec 19, 20190183;32;The flotation percentage of PVC sharply increases to 100 % within 5 min. However, the flotation percentages of PC, PS, and ABS remain 0 % with the increasing flotation time, which indicates the floatability of PC, PS, and ABS is unaffected by flotation time. The flotation percentage of PVC can be 100 % at flotation time of 4 min.

Microwave assisted extraction in natural products isolation.

Microwave assisted extraction (MAE) or simply microwave extraction is a relatively new extraction technique that combines microwave and traditional solvent extraction. Application of microwaves for heating the solvents and plant tissues in extraction process, which increases the kinetic of extraction, is called microwave assisted extraction.

Microwave Assisted Carbothermal Reduction of Banded

Sep 16, 20190183;32;This study investigates the microwave carbothermal reduction of low grade banded hematite jasper iron ore (Fe ~ 37%). The susceptibility of iron phases to microwave exposure and their selective absorptions help in the liberation of iron values from impurities. It was found that a small fraction of the microwave irradiated ore charcoal mixture was rapidly melted to produce pure ferrite balls

Microwave Heating Applications in Mineral Processing

2.5. Microwave assisted pretreatment of refractory gold concentrate. Gold is considered to be refractory when it cannot be easily recovered by alkaline cyanide leaching. The vast majority of refractory gold occurs in sulphidic minerals such as pyrite (FeS 2), arsenopyrite (FeAsS) and pyrrhotite (FeS).

Microwave chemistry

Microwave chemistry is the science of applying microwave radiation to chemical reactions. Microwaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid.Polar solvents are heated as their component molecules are forced to rotate with the field and lose energy in collisions.
