The 5 Main Steps in Processing Diamond Ore | Multotec
Nov 12, 2018· Here are the main steps in processing diamond ore. A number of these processes use equipment from Multotec: 1- Crushing. The first step in kimberlite ore processing is crushing. This process reduces large run-of-mine lumps into smaller pieces, making them easier to handle, and releases or liberates the diamonds to be recovered in subsequent steps.
Ore - Wikipedia
Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.
Extractive metallurgy - Wikipedia
Mineral processing begins with beneficiation, consisting of initially breaking down the ore to required sizes depending on the concentration process to be followed, by crushing, grinding, sieving etc. Thereafter, the ore is physically separated from any unwanted impurity, depending on the form of occurrence and or further process involved.

Uranium Mining and Extraction from Ore
Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding. The roasting process is meant to burn carbonaceous species trapped within the ore and make the ore more reactive to the leaching treatments.
