Concentrating Plant Design — Capital and Operating Costs ...

Abstract. Present design of concentrating plants is briefly dealt with, emphasizing the different factors which seem to be most important in these days of high labour costs and reduced availability of low-cost energy. Such items as autogenous and semi-autogenous grinding, two-stage classification, large flotation cells, pressure filtration, etc ...

Assessing the Total Cost of Representativity in Flotation ...

Jan 01, 2017· Jan 01, 2017· The proposed framework, referred to as the total cost of representativity, answers the previously unanswered question of how much accuracy/reproducibility is fit for purpose in a given flotation plant. Authors readily acknowledge that it is way easier to assess the cost of accuracy/reproducibility than the cost of inaccuracy/irreproducibility.
