Outotec SkimAir is a flotation cell designed to be installed in a flash flotation role in the grinding circuit. The cell is typically installed on the hydrocyclone underflow stream to capture any sufficiently liberated, fast floating particles that may have reported here.
A copper mine in South America partnered with Nalco Water to help achieve their operational goals. The goals included improving recovery through their copper flotation circuit, increasing productivity, and ultimately reducing the total cost of operations while ensuring a safe production environment.
Several large tonnage copper porphyry plants in Chile use an open-circuit SAG configuration where the pebble crusher product is directed to the ball mills (SABC-B circuit). The original grinding circuit at Los Bronces is an example: the pebbles generated in the two SAG mills are crushed in a satellite pebble crushing plant, and then are ...
