A process for producing phosphorus pentoxide from phosphorus ore includes formation of a feed with a phosphate ore, silica and solid carbonaceous material in amounts to produce a feed mixture having a CaO/SiO 2 mole ratio of less than about 0.5. The feed mixture is formed into agglomerated feed particles and the particles are heated by exposure to radiation eminating from an oxidation zone to

Sep 23, 2020 Primary economical deposits of rare-earth elements (REEs) are exhausting all over the world, and it has become necessary to find new sources and methods for their extraction. In addition, increasing the application of REEs in modern technological society has increased its demand globally. One of the important movements to compensate for the future shortages of critical metals is the

Oct 22, 2019 Whatever attempts may be made to solve distribution-related problems, they will be undermined if population growth continues, for two reasons. First, population growth and the aggravation of distribution problems are correlated—part of the increase will surely be absorbed in urban areas that can least afford the growth

Jul 03, 2013 On an average global basis, iron ores tend to decrease in Fe grade over time. With the exception for some deposits that are logistically challenged, iron ore resources in more accessible areas may often have processing issues, especially if high-grade concentrates are desired. This paper addresses some of these with examples on how technological developments enhanced the feasibility

Jan 30, 2019 Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity
