Interactive effect of minerals on complex ore flotation A

Interactive effect of minerals on complex ore flotation A

Oct 13, 2019 Iron ore flotation is a complicated procedure. The presence of fine or ultrafine particles adversely affects iron ore flotation, which is probably due to the heterocoagulation and covering of fines. This process leads to variation in mineral surfaces, resulting in a low separation efficiency.
