冶金、化工工艺过程中,如溶出,锈蚀、气相挥发,某些选矿等,都遇到物料元素组分提取率的计算问题。所处理的物料多是由多元素组成。在提取工艺过程中,组成物料的各元素组分都或多或少由固体颗粒被迁移到提取介质中,情况是很复杂的。现以原物料和提取渣为基准,从理论上导出元素组分提取率通用的基本计算公式。
Metallurgical and chemical processes, such as dissolution, corrosion, vapor phase volatilization, some of the beneficiation, etc., have encountered the calculation of the extraction rate of the material element composition. The material handled by more than a multi-element composition. In the extraction process, the composition of the material components of the elements are more or less from the solid particles are migrated to the extraction medium, the situation is very complicated. Now based on the raw materials and extracted slag, the basic calculation formula for the extraction rate of elemental components is theoretically derived.
