Lead and Zinc Department of EnergyUranium mines and mills Canadian Nuclear Safety Commission

61 Process Overview 611 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface Lead and zinc ore is mined almost exclusively in underground operations though a few surface operations do exist The use of underground or surface mining An example of an area the CNSC regulates is radon exposure in uranium mines and mills The CNSC requires licensees have engineering design and control processes to remove radon to limit exposure to workers Radon is naturally produced by the decay of uranium and is released into the air when uranium ore is mined and milled Radon gas produced during mining and milling is continuously monitored

Fine Ore Storage Bin and Stock PileGrinding in Ball Mills Modeling and Process Control

To complicate this process the ore is being pulled from the DRAW POINTS these are the feeders that control the rate of flow of the ore as it leaves the storage area What this does is guide the ore to these points Much like the current you would find in a pond where there is a discharge creek The maximum amount of movement is directly in front of the exit point The effect of the current The design of a ball mill can vary significantly depending on the size the equipment used to load the starting material feeders and the system for discharging the output product
