摘要：

The effect of high concentrations of sodium carbonate in soda ash digestion of scheelite concentrates has been studied by analysing the temperature profile through the calcium carbonate ash layer, and using a calcium sequestering agent (EDTA) in the leaching system. A mechanism based on the principles of the adsorption phenomena involved is described to justify the probable presence of a double compound of sodium and calcium carbonates blocking the calcite pores.
