Discription of ore separation spiral classifier. The ore separation spiral classifier is widely used to pre-grading and inspection grading in closed circuits when used in the production flow of metal processing.According to the difference in sedimentation rate of mineral particles and mud the particle sies of ores with 1.5mm-0.03mm are .
Increasingly stringent environmental regulations and industry adoption of waste minimiation guidelines have thus stimulated the need for the development of recycling and reuse options for metal related waste.
The mineralogical and chemical characteristics of the feed coals and coal combustion products CCPs from two power plants Xilaifeng and Damo that consume coals from the Wuda Coalfield Inner Mongolia were investigated using XRD SEMndashEDS XRF and ICP-MS. The feed coals from Xilaifeng and Damo are both of high ash yield 52.93 and 48.

Inhalation exposure to 100 mghr aluminium in the form of powder or 92 mg Al per 2 hr as a fume each day for 9-13 months showed a significant retention of aluminium in the lungs of both groups of animals. The aluminium retention in the lungs in rats and hamsters exposed to fume was much greater than when exposed to powder.
