The production function is a short-run production function because it illustrates what happens to output as more and more units of the variable input, labour, are added to the fixed stock of capital. Thus Fig. 13.2 is a graphic representation of equation (2) which is the short-run production function for radios.

Ore extracted from the Andoom (Weipa) deposit is processed through a beneficiation plant to remove the finer fraction; these finer particlesParticles will otherwise lead to material handling problems. A key component of the beneficiation flowsheet is a fluidized bed classifier, where fine particlesParticles are removed via an overflow system.
Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
Ore washing and beneficiation may yield pro-cess wastewaters containing suspended solids. Runoff from precipitation may also contain sus-pended solids. At the alumina plant, air emissions can in-clude bauxite dust from handling and process-ing; limestone dust from limestone handling, burnt lime dust from conveyors and bins, alu-

Like the Sishen plant, the Mount Tom Price plant utilizes ferrosilicon as dense medium. A coarser grade (65D) is used for the drum plant and a finer grade (150D) for the cyclones. The efficiencies for the RTIO DMS plants also exhibit typically very small E p s—in the region of 0.05–0.1 kg/dm 3.
Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Beneficiation The fast movement of the slurry causes it to bang against the pipes, and this breaks apart any clay balls. What arrives at the beneficiation plant are fine-grained sand, clay and phosphate sediments suspended in water. At the beneficiation plant, the slurry is first run through a screen, which filters out the coarser sand.
Amrun Bauxite Project, Cape York, Australia. The Amrun bauxite project (formerly South of Embley Project) is located near Boyd Point, 40km south of the existing Weipa mine and 40km north of Aurukun on the Cape York Peninsula in Far North Queensland, Australia.
