The sand tailing from the mill is treated by ammonia leaching and the slime tailing by ...
The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams. Material in process often cannot be weighed without a ...
As mentioned above, mineral processing of lead vanadate ores is often limited to gravity concentration methods, which causes substantial losses in slimes and intergrown particles. Therefore, flotation is applicable for the beneficiation of fine-grained lead vanadate ores and the recovery from slimes.
