The carboninpulp process is used to treat low grade gold and/or silver ores. The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device. This is done to produce a feed suitably sized so that subsequent leaching is rapid.
of chemically milled pieces, optimize acid bath life, and determine any trends between the two. Accurately determining metal removal rates would result in a more efficient and less time consuming chemical milling process. Based on results, it was determined that alpha case plus the titanium alloy is removed during chemical milling.
By modifying the extrusion process conditions, studying high solids coagulation and optimizing the coagulation and washing steps, acid casein of an acceptable quality can be produced by extrusion. This process is continuous, controllable, uses high solid SMP and may reduce labour and floor space requirements relative to conventional processes.
This helped solidify the design for a flexible system (one stage without washing, two stages with acid washing, or two stages with acid washing and drying). Depending on the intended use of the lignin, ANDRITZ tailors the Lignin Recovery system to achieve a mill''s exact goals.
