Rough Diamond Ore Processing
Rough Diamond Ore Processing and Treatment. Several techniques are used to process the diamantiferous ore. The techniques used will not be the same between artisanal and industrial mining, however there are some common elements: Crushing, not too fine (rough diamond must not be crushed). Screening separates the sand from large elements.
Processing
The screening process is done for both alluvial and conglomerate. Alluvial screening is done to remove excessive fines content and oversize material. The resultant product is alluvial diamond concentrate with required particle sizes. Conglomerate screening is done to remove fines and oversize material. The screens are part of the crushing and ...
How Are Diamonds Mined and Processed?
Post the scrubbing, these ores are screened to process further. After the crushing process, the ore is sized with the help of vibrating screens. Most of the time, wet screening is preferred. This is because the ore extracted from mining diamonds is already wet, and using wet screening eliminates the need for any dust control in the process.
How are diamonds separated from ore? | DMS Powders
Once the ore is retrieved, the diamond processing begins. The different phases in separating diamonds from ore include: Phase 1 – Crushing of the ore: The diamond-bearing ore is transported to a primary crusher, to crush the ore in to smaller particles, making it easier to handle (no bigger than 150mm). Phase 2 – Scrubbing and screening ...
