Uranium Mining and Milling Wastes An Introduction

Most uranium ore is mined in open pit or underground mines The uranium content of the ore is often between only 0 1 and 0 2 Therefore large amounts of ore have to be mined to get at the uranium In the early years up until the 1960 s uranium was predominantly mined in open pit mines from ore deposits located near the surface

Selection and mathematical modelling of high efficiency

The performance of an air classifier is evaluated by drawing the actual efficiency curve or Tromp curve that explains what portion of the material in the feed subjects to the underflow or overflow streams at a given size fraction The x axis of the curve denotes to particle size and the y axis denotes to the probability for being separated as fines and coarse
