quartzite used in plant

Steep (backside) quartzite ridges standing as stony (nothing other than hard massive quartzite) barren (no trace of plants and forest) standing 50 m above valley level (500 m above main sea level). The quartzite ridge is sitting at the top of a rich metal grade deep-seated orebody of 60 Mt averaging 5% Zn, 3% Pb, and 215 g/t Ag that starts at a depth of 120 m from valley level.

Selective leaching kinetics and upgrading of low-grade calcareous …

2005. 12. 30.· The by-products, CO 2 and calcium sulphate may be used or sold to other industries to meet the cost of commercial succinic acid and its recovery by sulphuric acid. The selective leaching process can be simplified using the following general equations: (1) MCO 3 (s) + H 2 Y(aq) → MY(s/aq) + CO 2 + H 2 O (2) M 3 (PO 4 ) 2 + 3H 2 Y → 3MY(s/aq) + 2H 3 PO 4 where M = Ca 2+ and/or Mg 2+ , Y = H 2 C 4 O 4 2− (succinate).
