查询词典 copper bearing

It was rev ealed that:cuprite,malachite and tenorite are the three main kinds of copper-bea ring minerals which would be supersaturated when Cu concentration in the solutio n is high enough(higher than 0.0016 mol/L,0.0079 mol/L separately) under the stu dy conditions.Copper exists in the solution mainly as the species of CuCO3 ,Cu2+ and CuOH+.The corresponding content of CuCO3 would be decrea sed following the deposition of the copper-bearing minerals,nevertheless,Cu2 + and CuOH+ would be increased.
