Water Pollution Caused by Inactive Ore and Mineral Mines
ABSTRACT The report identifies the scope and magnitude of water pollution from inactive ore and mineral mines. Data collected from Federal, State, and local agencies indies water pollution from acids, heavy metals, and sedimentation occurs at over 100 loions and affects over 1,200 kilometres of streams and rivers.
US20090008301A1 Methods of Increasing Flotation Rate
Methods of increasing the rate of separating hydrophobic and hydrophilic particles by flotation have been developed. They are based on using appropriate reagents to enhance the hydrophobicity of the particles to be floated, so that they can be more readily collected by the air bubbles used in flotation. The hydrophobicityenhancing reagents include low HLB surfactants, naturally occurring
