A novel switchable collector for selective flotation of fine copper
The flotation performance of fine copper oxide from silica using T-OA was studied by micro-flotation tests. The adsorption of T-OA on copper oxide was investigated by zeta potential determination and QCM-D measurements. The switching of T-OA activity on copper oxide surface was further demonstrated by contact angle measurement.Residual copper is gradually enriched in short steelmaking and produces copper crunch.

CN102408123A Preparation method of superfine copper oxide
The invention relates to a preparation method of superfine copper oxide powder. In the preparation method, copper ore is used as a raw material, the superfine copper oxide powder is prepared by adopting a spray baking method, and at the same time, the tail gas generated in a spray baking process is absorbed and returned to a production system for From these perspectives, sintering of copper fine particles/nanoparticles to form electroconductive layers has been intensively studied in recent years. 14,18–20,26–30 The inner electrodes of a multi-layered ceramic copper oxide layers on the surface of copper nanoparticles prevented necking formation and an increase in conductivity.The role of surface oxides and stabilising carboxylic acids of copper
