North Pennines

The principal centres of lead mining in this county were in Teesdale and Weardale, where most of the ore came from similar strata to those found in the mines of east Cumberland. The Bishop of Durham, owner of the minerals in upper Weardale from the mid 12th century, formalized earlier arrangements in 1566 by letting them to a Moor Master who oversaw the allocation of mining rights and the

Uranium Recovery

21-09-2020This happens either in a uranium mill (the next step in processing ore from a conventional mine) or during in situ recovery (ISR). For that reason, the NRC regulates in situ recovery facilities (as stated above), as well as uranium mills and the disposal of liquid and solid wastes from uranium recovery operations (including mill tailings).

Uranium Mining and Milling Wastes: An Introduction

MILLING OF THE ORE Ore mined in open pit or underground mines is crushed and leached in a uranium mill. A uranium mill is a chemical plant designed to extract uranium from ore. It is usually located near the mines to limit transportation. In the most cases, sulfuric acid is used as the leaching agent, but alkaline leaching is also used.

Rod mills are very similar to ball mills, except they use long rods for grinding media. 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.

Personal and area samples for airborne lead were taken at a lead mine concentrator mill, and at a lead-acid battery recycler. Lead is mined as its sulfidic ore, galena, which is often associated with zinc and silver. The ore typically is concentrated, and partially separated, on site by crushing and differential froth flotation of the ore minerals before being sent to a primary smelter.
