ways of increasing the hardness in an aquarium. by robert boumis .coral sand and calciumrich rocks like tufa rock and limestone can raise the hardness of aquarium water by slowly leaching minerals into the water that harden it. for this reason these rocks and substrates are popular for saltwater tanks and african cichlid aquariums
cil gold processing plant mainly consists of following steps: 1 the ore is first reduced in size typically 90% passing 200meshto ensure that all nonrefractory gold is readily accessible for cyanide leaching there are several variations of comminution circuits used in the gold leaching industry such as: multistage crushing then ball milling circuits typical of ball mill and hyrocyclones.
leaching is also used to remove metals from their ores. in one procedure certain crushed ores of copper are placed into a series of tanks. as a solvent such as sulfuric acid is pumped into the first tank it dissolves the copper from the ore. eventually overflowing the first tank the solution passes into the second where more copper is
