Using Nanotechnology For Rock Phosphate Processing

An attempt was made in the present investigation to utilize the vast deposit of rock phosphate (RP) of India by preparing nano RP using modern tool of nano-science and nano-technology for field application to maize crop (Zea mays L.). To evaluate the efficacy of different nano RP, a field experiment was conducted during kharif season (June to September) of 2012 at India Institute of Soil

    New Rock Phosphate Process Extracts Fertilizer Feedstock

    Mar 27, 2019 Current bulk phosphate fertilizers are typically manufactured using a wet acid process. This requires sulphuric acid from rock sulphur to dissolve the phosphate and precipitate gypsum. The new smelting process removes the need for sulphur as a feedstock. Instead the new process uses a ‘thermal process route for smaller scale processing of low
