Flotation process of the copper oxide ores using nonionic polymer

摘要

Provided is a process of sorting a float of a copper oxide ore using non-ionic polymer without the use of activators and collecting agents which are harmful to humans and the environment. The process of sorting a float of a copper oxide ore using non-ionic polymer comprises: a step of manufacturing suspensions containing gangue minerals and useful minerals including copper respectively; a step of mixing the gangue minerals and the useful minerals with a solution having the non-ionic polymer in a chamber, and dispersing the mixture; a step of generating bubbles by injecting nitrogen gas into the chamber; and a step of selectively adsorbing the useful minerals in the bubbles. In addition, the process of sorting a float of a copper oxide ore using non-ionic polymer comprises: a step of manufacturing a suspension containing gangue minerals and useful minerals including copper; a step of mixing the gangue minerals and the useful minerals with a solution having the non-ionic polymer in the chamber, and dispersing the mixture; a step of generating bubbles by injecting nitrogen gas into the chamber; and a step of selectively adsorbing the useful minerals in the bubble.
