Types of Ore

Ore is rock that contains economic amounts of a particular element, e.g. gold ore, iron ore, molybdenum ore, or praseodimium ore. In contrast, rock that is not judged to contain economic quantities of an element is categorized as waste rock. The metals in ore can occur in many different minerals (compounds) in the rock. As an example, copper occurs in more than 50 minerals Get price

Uranium Mining Overview

Mill chemistry. The crushed and ground ore, or the underground ore in the case of ISL mining, is leached with sulfuric acid: UO 3 + 2H + ==== UO 2 2+ + H 2 O UO 2 2+ + 3SO 4 2-==== UO 2 (SO 4) 3 4-. The UO 2 is oxidised to UO 3.. With some ores, carbonate leaching is used to form a soluble uranyl tricarbonate ion: UO 2 (CO 3) 3 4-.This can then be precipitated with an alkali, e.g. as sodium Get price

What are the main methods of mining?

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
