In India, Ayurveda, Siddha and Unani (ASU) systems of medicine are considered to be the oldest system of medicines. They prescribe drugs of herbal, mineral, metallic and animal origin for the treatment of many diseases. Being time tested systems of medicine and majority of the drugs used by them are of herbal origin these systems are considered to be safe. The use of ASU medicines continues to ...

CaIrO3-type MgSiO3 is the planet-forming silicate stable at pressures and temperatures beyond those of Earth's core-mantle boundary. First-principles quasiharmonic free-energy computations show that this mineral should dissociate into CsCl-type MgO cotunnite-type SiO2 at pressures and temperatures expected to occur in the cores of the gas giants + and in terrestrial exoplanets. At approximately...

From DFT based calculations establishing energy-volume equations of state, a proposition of high pressure candidate structures with reduced volumes, namely columbite and trirutile are proposed for fordite mineral SnNb2O6. The key effect is the destabilization of divalent tin in fordite towards tetravalent state upon compression. This is helped with smaller size tetravalent tin. The remarkable e...

This paper is concerned with the approach followed in Western Australian for dealing with the environmental hazards of ionising radiation associated with the mining and processing of titaniferous minerals contained in mineral sands deposits. There is a growing public awareness of the risks posed by one of these minerals, monazite, which emits low levels of radiation as it contains thorium and u...

(2008), doi:10.1016/j.minen Froth flotation for beneficiation of printed circuit board comminution fines was investigated in this work, via reverse flotation under a scheme described as natural hydrophobic response. With no reagents, the scheme employed variation of kinetic parameters of airflow rate and impeller speed to optimize m...

A systematic analysis of the mineral resource base (MRB) strategically important minerals for Ukrainian economy is carried out. Four categories strategic from point view their investment attractiveness are identified: traditional (iron, manganese, titanium, uranium, kaolin, sand molding, building stones, quartz raw materials, refractory clay); highly promising (rare earths, zirconium and hafniu...

Pressure-driven processes have come a long way since they were introduced. These processes, namely Ultra-Filtration (UF), Nano-Filtration (NF), and Reverse-Osmosis (RO), aim to enhance the efficiency of wastewater treatment, thereby aiming at cleaner production. Membranes may be polymeric, ceramic, metallic, or organo-mineral, filtration techniques differ in pore size from dense porous membrane...
