HEAP LEACHING TECHNIQUE in MINING

In response to ever increasing prices of base metals like copper, nickel, cobalt and precious metals, heap leaching has become a major beneficiation technique used for large tonnage-low grade (generally 0.5 to 1 gr/ton) ores which cannot be economically processed through tank leaching.get price

Mining Waste an overview ScienceDirect Topics

According to published incomplete data (not including the USA and 10 other countries), among 19 of the 30 OECD member states (OECD, 1997, 1999), Canada held the dominant position in the amount of mining waste generated annually (~65.4% of the total); 23 member states of OECD Europe produced 402.4 Mt, which was about 25%, while 15 EU member states generated 19.0% of the total OECDget price

Chemical Beneficiation of Phosphate Rock E & MJ

Uranium, Rare Earths, Radium, FluorineProduction of Dicalcium PhosphateUsing Phosphoric AcidSummaryReferencesMethods have been devised to recover uranium and rare earths by extraction with organic solvents while radium can be co-precipitated with barium sulphate. Under the mild leaching conditions used in this process, HF in solution reacts with silica to form fluorosilicic acid: which can be precipitated with sodium nitrate to form sodium hexaflurosilicate:
