The estimated output was 30 tons of washdirt per hour, and the labour one man per shift. The sluicing water was raised in small buckets attached to the rim of the current wheels. In the part of the river operated on, the stream was very rapid from side to side, and enabled the dredge to do all that a steam machine could and at much lower cost.
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue
The effect of resuing, involving the breaking of considerable wall rock and resulting in low tonnage per manshift, and added costs for sorting in the stopes, is indicated by the costs RRR. The points used for determining the shrinkagestoping curve are seen to be quite erratic in their distribution, few of them actually falling on the approximate mean curve.

The state processes a range of mineral products making up approximately 1.2 per cent of Tasmanias Gross State Product. A survey by the Tasmanian Minerals and Energy Council identified that the industry spent $429 million on goods and service s in Tasmania over the 201011 period, as well as $50 million on capital projects. Over this period, the mineral processing sector used the services of
The International Journal of Mineral Processing covers aspects of the processing of mineral resources such as: Metallic and nonmetallic ores, coals, and secondary resources. Topics dealt with include: Geometallurgy, comminution, sizing, classification (in air and water), gravity concentration, flotation, electric and magnetic separation
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
The air bubble and mineral particle rise through the pulp to the surface of the froth or foam that is present on the flotation cell. Even though the air bubbles often break at this point, the mineral remains on the surface of the froth. The mineral is physically separated from the remaining pulp material and is removed for further processing.
