ThisBureauofMines report anditscompanion report (Information Circular 9142) have been preparedtoassist in the preparationofprefeasibility type estimates for capital and operating costsofbeneficiationofvarious typesofmineral occurrences using current technology. Thehandbook providesaconvenient costing procedure basedon thesummation of the costs for the unit processes required in any particular mining or mineral processing operation.

Thecosting handbook consistsof aseriesofcosting sections, each correspondingto aspecific mineral processing unit process. Contained within each sectionis themethodologytoestimate either the capital or operating cost for that unit process. Theunit process sections maybeusedtogenerate, in January 1984 dollars, costs throughtheuseofeither costing curves or formulae representing the prevailing technology.

Themineral processing handbook includes individual cost estimation sections for unit operations associated withcomminution,,beneficiation, solid-liquid separation, hydrometallurgy, and special applicationsaswellas infrastructure and plant general and administrative costs. When using this system for estimating cost data fora mineral processing facility or for checkingorverifying processing costs from an existing facility,aminimum amountofbackground informationisnecessary.
