Waste rock content
-
The paper presents a brief description of an automated system, designed to control coal quality in accordance with the specified parameters of the waste rock content owing to obtaining, collecting, processing and storing information from primary instruments, using a radioisotope measuring method.

An experiment was conducted at the experimental farm of Department of Soil Science, CSKHPKV, Palampur by taking French bean crop during kharif, 2009. Biocompost and vermicompost were prepared by using cow dung and weeds and were inoculated with microbial inoculants and rock phosphate. Biocompost and vermicompost were analysed and the best one among nine composts prepared i.e. 50% each of cowdung and substrate+ 2% rock phosphate + inoculants and three vermicomposts i.e.

Beneficiation (or concentration) processes are gener- ally used to upgrade the phosphate content by removing contaminants and barren material prior to further processing. A few ores are of sufficiently high quality to require no further concentration. The natu- rally occurring impurities contained in phosphate rock ore depend heavily on the type of deposit (sedi- mentary or igneous), associated minerals, and the extent of weathering. Major impurities can include organic matter, clay and other fines, siliceous material, carbonates, and iron bearing minerals.
