title = "effect of autogenous and ball mill grinding on sulfide flotation.", abstract = "the effects of grinding on the floatabilities of copper-nickel sulfides from duluth gabbro were investigated. at the same mesh-of-grind copper, nickel, and cobalt recoveries were higher and residual sulfur in the tailings was lower with autogeneously ground pulps.
ball mills give a controlled final grind and produce flotation feed of a uniform size. ball mills tumble iron or steel balls with the ore. the balls are initially 5 10 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

4 froth flotation circuit design and basic testwork requirements skimmed off as a mineral-laden froth. the remaining unfloated mineral slurry will be discharged as tailings. most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage
in grinding, the use of steel media in a rod/ball mill circuit clearly diminishes the subsequent froth flotation performance over purely autogenous grinding. the use of recycle water in grinding also clearly diminishes the subsequent froth flotation performance associated
the crushed ore after automatic sampling is subjected to two-stage grinding using a rod mill in open circuit and a ball mill in closed circuit with a classifier. the unit flotation cell receives the discharge from the ball mill for recovery of a substantial amount of the

this consists of a grizzly, followed by single stage crushing, and fine grinding in a closed ball mill-classifier circuit. the classifier overflow passes to a conditioner, and then to a sub-a flotation machine, where a high grade concentrate and low tailing are made.
