Milling This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining The ore is brought to a mill crushed and ground up before chemicals are added to dissolve the uranium The uranium is then separated from the chemical solution solidified dried and packaged
The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 1 4 to 1 6 Rod mills accept feed up to about 50 mm (2 in ) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh
Feb 01 2010 In the case of copper ore it is the crushing and grinding (particularly the latter) steps that make the largest contribution (approximately 46 ) to the total greenhouse gas emissions for the mining and processing of copper ore (628 kg CO 2 e t concentrate) These results indicate that efforts to reduce the increased greenhouse gas emissions
