CHARACTERIZATION OF TALC-CARBONATE ROCK OF MINGORA EMERALD MINES, DISTRICT SWAT, KHYBER PAKHTUNKHWA, PAKISTAN

...nates like magnesite and calcite as associated impurities. Optimum grinding time at which talc particles get liberated from gangue is 60 minutes and whiteness of the original rock is 50 to 60%.

EXTRACTION OF HIGH QUALITY TALC FROM TALC-CARBONATE ROCK OF MINGORA EMERALD MINES BY FLOTATION AND LEACHING

...minerals like magnesite, calcite, dolomite, quartz, muscovite, chlorite, tremolite and iron bearing minerals. These associated minerals determine the quality of talc for industrial purpose and if in access, limits its applications. In present research work, beneficiation studies of carbonatic talcose rock of Mingora emerald mine located in District Swat, Khyber Pakhtunkhwa (KP), Pakistan were conducted to recover high quality talc out of the talc carbonate roc...

RECOVERY OF TALC FROM TALC- CARBONATE SCHIST OF SWAT EMERALD MINES, NWFP, PAKISTAN

...mines talc rock contains calcite, magnesite, dolomite, muscovite and quartz as impurities. Talc content in the original rock ranges from 60 to 65% and possible to liberate at grind size of 45 microns. Flotation test results revealed that talc upgraded to 85% with 80% recovery using frother as a process aid whereas, upgradation using gravity separation was 82%. The flotation concentrate on leaching further improved and the level of impuritie...

Simple Bulk Storage Methods to Maintain the Physical Properties, Botanical Component, Nutrient Content, and Nutritional Values of Rice Straw Supplemented with Calcite-Based Minerals, Molasses, and Urea

Khalil¹*, Dwi Ananta¹, Andri Bachtiar², Hermon³

...raw supplemented with 1% calcite-based mineral mixture, 0.6% molasses, and 0.05% urea. The supplemented straws were stored for 60 days in three bulk treatments: loose stacking, open-tied rolling, and airtight wrapping. The changes in physical appearances, botanical fraction, proximate, and fiber fraction content were determined. The nutritive values of stored rice straws were evaluated by feeding four male Indonesian-indigenous Pesisir cattle in a 4x4 Latin Sq...

Calcined Mussel Shell from Corbicula Sumatrana, A Natural Preservative and Mineral Supplement of Fishmeal for Feeding Laying Quails

Khalil¹*, Ridho Kurniawan Rusli², Montesqrit², Andri³

... evaluated by mixing the calcite-preserved fishmeal with a basal diet of 5% and feeding it to 200 laying quails for eight weeks. The feeding trial had four treatments as a basal diet combined with fishmeal containing 0, 3, 6, and 9% CMSM. Each treatment was composed of 5 replications (@ ten birds). Parameters measured included feed intake, egg production, FCR, eggshell, and tibia bone mineralization. Results found that 3-9% CMSM increased crude ash and densiti...
