Research paper thumbnail of MAGNESITE AS SOURCE OF MAGNESIUM NUTRITION FOR FENUGREEK

Presented in International Conference of Mineral Process Technology, Visakhapatnam, 2014, 2014

Table 1 - Magnesite as source of Mg nutrition for fenugreek Water washed sea sand of 350 grams was used as substrate soil. The pH of absolute control is approximately 8. Magnesite at 0.25 and 0.5 grams doses was tested with and without the back ground of 10 grams of organic matter as shown in Table 1.

Research paper thumbnail of A Brief Review of Phosphate Rich Organic Manure, 2016

Research & Reviews: Journal of Agricultural Science and Technology ISSN: 2278-2206(Online), ISSN: 2349-3682(Print) Volume 6, Issue 1 www.stmjournals.com, 2016

Phosphate Rich Organic Manure (PROM) has been in the frame of organic farming since last two decades and is challenging synthetic chemical fertilizers like DAP, MAP, SSP, and Nitro-Phosphates. PROM is essentially high-grade rock phosphate mineral in fine size along with well-matured organic manure. Bacillus megatherium, varphosphaticum (phosphate solubilising bacteria), Azotobacter (nitrogen fixing bacteria) etc. may be added to improve the efficacy of PROM. Well-matured organic manure has C:N ratio at 20:1. The aim is to illustrate step-by-step process of manufacturing phosphate rich organic manure (as a marketable product)with government specifications as mentioned in fertilizer control order (FCO).

Research paper thumbnail of Soap Flotation: A Brief Review

Journal of Modern Chemistry & Chemical Technology ISSN: 2229-6999(online), ISSN: 2321-5208(print) Volume 7, Issue 2 www.stmjournals.com, 2016

Straight chain saturated fatty acid anions are envisaged to form compact adsorbed patches on the mineral surface, which are more effective in imparting surface hydrophobicity to the minerals than the loose/fluffy patches formed by unsaturated fatty acid anions that are bent at the double bonds. Addition of detergents or certain hydrotropes along with fatty acid/soap collectors reduces the consumption of fatty acids/soaps and thereby improves selectivity of mineral separation.

Fig. 1: (a) Compact Layer of Adsorbed Saturated Fatty Acid Anions on a Mineral Surface; (b) Fluffy Layer of Adsorbed Mixed Fatty Acid Anions on a Mineral Surface. Soaps and fatty acids used in the mineral industry as collectors are rather poorly specified. Usually the specifications are limited to TFM, IV and Titre Point/ TV and sometimes unsaponifiable matter, free alkali and moisture are also specified for soaps.

Nepheline syenite mineral2 contains 5.58% K2O, 8.23% Na2O. The K in nepheline Syenite is not in readily water soluble form. Proof of concept studies are conducted to see if fine sized nepheline syenite mineral can be used as source of K nutrition with the back ground of organic manure in the bio mass production of Spinach3, Spinacia oleracea. These results are compared with laboratory grade KCl on equal K2O basis.
