Copper and cobalt demand is projected to be increased from here 2050 the challenge find treat economically minerals which contains those metals. Several tailings oxide ores throughout word contain good grades of copper that should recovered by froth flotation. This paper investigates recovery through reprocessing spiral classifier determination specific reagents dosage. The flotation behaviours...

Froth floatation is an important process used in the mining industry for separating minerals from each other. The separation process is based on rendering a selected mineral hydrophobic using an appropriate hydrophobizing reagent (collector), so that it can selectively attach onto the surfaces of a rising stream of air bubbles. Thus, controlling the hydrophobicity of the minerals to be separate...

This work describes the concentration of iron ore slimes on a pilot scale by using 500-mm diameter flotation column and novel collector, which renders use depressant unnecessary. The was operated in series with industrial plant Vargem Grande 2 (Iron Quadrangle, Brazil) receiving, as feed, part underflow from desliming thickener. These tests represented only rougher stage circuit. collector used...

Waelz slag is an iron-containing waste generated during electric arc furnace (EAF) dust processing in a rotary kiln named the process. This study focuses on reduction smelting of to produce iron-based alloy. The thermodynamic simulation using FactSage 8.0 software was carried out predict temperatures metal and obtained as well their compositions. Based results, experiments were performed labora...

Flotation processes are difficult to model at a fundamental level and at present automatic monitoring and control of industrial plants have met with limited success. In practice these processes are most often controlled by human operators who tend to assess the performance of the plant based on their own experience and other heuristic rules. As a result plants are usually not controlled optimal...
