Bauxite Beneficiation: An Approach to Value Addition in Mining,o homogeneous nature and consistent quality, some alumina refineries prefer washed ore compared to simple crushed run-of-mine (ROM) bauxite. Non-metallurgical bauxite ore is generally sold at higher prices, and consequently can offset lower recovery and higher beneficiation costs. The primary object

Recovery of Valuable Metals (Rare-Earths) from Phosphate Fertiliser Waste (Phosphogypsum), content of REE in phosphogypsum waste is rather low. Nevertheless, it is significant in view of its huge quantity, as manufacturing of 1 tonne of phosphoric acid generates approximately 4.5–5.5 tonnes of phosphogypsum waste. It is possible to easily take out nearly 50% rare earths from phosphogypsu

Reduction of Hexavalent Chromium Using Microbial Remediation: A Case Study of Pauni and Taka Chromiium toxicity. Biotransformation of Cr (VI) to Cr (III) using bacteria is the most practically efficient approach. Ability of the bacteria to tolerate the chromium and to reduce it further into more tolerable species makes it very useful agent for remediation of the chromium contaminated soils. Impor
