Mesoporous zirconia was prepared by the surfactant-assisted route, using cetyltrimethylammonium bromide as cationic surfactant. The synthesized zirconia was employed as support for copper and nickel bimetallic-catalysts ...

Many reactive metals are difficult to prepare in pure form without complicated and expensive procedures. Titanium, in spite of its abundance and numerous favorable properties is not in use to the extent it deserves. This ...

Silicon carbide dendrite (micrometer size) is produced by carbothermic reduction of rice husk ash in an arc plasma. Transmission electron microscopy reveals the occurrence of equispaced primary arms (60-70 nm in length) ...

Hydrocyclone is a key unit operation in mineral-processing industry for beneficiation of mineral values that uses centrifugal force to separate materials by density or size. The optimization of different operating parameters ...

Flotation studies of non-coking coal using two non-conventional collectors, namely Polanga and Mahua oil, containing both saturated and unsaturated fatty acids are investigated. The effect of oil concentration, surface ...
