How to Remove Molybdenum Process Plant Water
2021-1-6 Total molybdenum remaining in flotation cell effluent is shown in table 1. Intense agitation was detrimental to molybdenum removal from water initially containing 10 ppm Mo, whereas this trend was not apparent using water initially containing 2 ppm Mo. Molybdenum precipitated from water initially containing 10 ppm Mo was nearly 98.5 pct, regardless of agitation intensity.
