Research in our laboratory has shown its applicability for preservation of virus The concept arrived is applied in processing of sugar-phosphate mixture by vacuum foam drying to obtain amorphous glassy matrix for model protein (Bovine Serum albumin, BSA) In VFD process, liquid samples are dehydrated by boiling under vacuum to form stable foams.
(a) Wet process Phosphoric acid is produced from fluorapatite, known as phosphate rock, 3Ca 3 (PO 4) 2CaF 2, by the addition of concentrated (93%) sulfuric acid in a series of well-stirred reactors This results in phosphoric acid and calcium sulfate (gypsum) plus other insoluble impuriti.
Direct drying processes are used in many industries, for example in the gypsum industry, the wood processing industry, the sugar, cement and potash industries or the phosphate industry In this drying process, flue gases from combustion come in direct contact with the material being dried to top.
• Sulfuric acid treatment process of bones and P minerals (apatite) was patented in mid 1800s • Today most P fertilizer production is based on acidification of apatite from phosphate rock (PR) Guano mining, Chincha Islands, Peru, 1860 Guano mining, Chincha Islands, Peru 1860 US phosphate.
1121 Phosphate Rock Processing 11211 Process Description1-5 The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining at some operations, and grinding The Standard Industrial Classification (SIC) code for phosphate rock processing is 1475 The.
