几年前,在伯加卡蒂迈·弗瑞堡地区就开始了寻找适合于萤石——方解石分离的捕收剂课题研究,并取得了重要成果,证实了N—酰胺基羧酸是萤石——方解石矿物分离的有效捕收剂。本文就所进行的试验室和工业性试验结果作一详细介绍。 A few years ago, the search for a collector suitable for the separation of fluorite-calcite began in the area of ​​Bieti-Mattie-Freiburg and achieved important results confirming that N-acylcarboxylic acid is a firefly Stone - Calcite effective separation of minerals collector. This article gives a detailed introduction of the laboratory and industrial test results.
