Wet ore or concentrates will reduce dust exposure, but people can be exposed to dust from dried spilled material, or generated from tailings storage facilities, product stockpiles and during product transfer. Some metals that are mined or present as processing reagents are potentially toxic if inhaled or ingested, such as lead, arsenic and mercury.

Aug 30, 2022The fine-grained gold or sub-microscopic gold in this gold ore is wrapped or disseminated in pyrite. Although pyrite is more floatable, even if it reduces the grinding fineness, it is challenging to achieve monomer dissociation, so it isn't easy to recover. It usually treats such minerals by multi-stage grinding and multi-stage separation.
