The mining test on a low grade uranium ore body by means of in-situ breaking down and leaching is explained in details including selection of ore body,muckpile formation through breaking down,feeding of leaching solution and leach-out,collection of leachate etc.

Research on treating leaching liquor of spent nickel-cadmium batteries with emulsion liquid membrane;

The authors can obtain the formula which is used to estimate the output of the leaching liquor when the underground gushing water is conside.

The Study on Leachate of Purification from Cobalt Pyrite Concentrate in Panzhihua;

In Chuanyu area,the simple solidification of the waste drilling mud produced condensate having leachate unable to reach the criterion for sewage discharge.

The pH value was found to be detrimental,and Fe 3+ concentration in leachate could reach about 30mg/L in the low limit of pH.

Extraction-electrowinning copper from cobalt copper ore leaching solution;

High concentration copper sulfate solution was prepared by solvent extraction using leaching solution of low grade copper ore.

Using solvent extraction to separate Fe3+ from the leaching solution of arsenic-bearing sulfide copper concentrate ore is an important step of the process for preparing copper arsenate.

Effect of the suspension and lixivium from ooze mud in the Changjiang estuary on chlorophyll a;

By means of orthogonal experimental design,the main cause of oil mass conˉcentration of lixivium is ratio and hours has been determined.

The experimental process included strength testing of the solidified block, and analysis of the lixivium for contents of COD, oil and toxic substances, i.
