What are Pregnant, Barren, and Processing Ponds?

By the time the solution moves to a long-term holding pond or a reuse tank, ore has been harvested as much as possible. Barren vs Pregnant. The solution exiting the leaching area first arrives in a processing pond for pregnant solution. When there's still a majority of harvestable ore left in the liquid, it's considered pregnant or loaded.

A clean non-toxic method for leaching of barium tungstate

Moreover, this method is theoretically proved to be feasible. Also, the leaching of barium tungstate experiment was carried out. Under optimum conditions with liquid/solid ratio 10:1 mL/g, reaction temperature 75 °C, and Na 2 SO 4 dosage 2.5–3.0 M times to BaWO 4, the leaching rate of barium tungstate was >99%. This method has the advantages ...
