tests which are closer in height to the proposed heap, and, if possible, large scale pilot heaps which are more representative in terms of physical performance of a full scale HLP. On several gold projects, reducing the column recovery by 5% and applying a scaling factor of three from the column leach cycle to represent the field leach cycle, has been a reasonable approach. The metallurgical ...

Run-of-mine ore from the pit and existing stockpiles is dumped with the addition of lime, onto leach cells in 15 m lifts. Material is dumped during nine months per year to avoid the coldest period, however irrigation of the heap is maintained year-round using buried piping and dripper systems.

Prevent Permeability Loss in Heap Leaching

The Bureau of Mines Twin Cities Research Center conducts research to assist in solving problems that occur during solution mining of metals. Solution mining of uranium involves injecting a carbonate-bicarbonate (basic) or sulfate (acidic) leach solution through injection wells into an ore body where the lixiviant dissolves the uranium from the ore.
