Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
This research aims to observe the beneficiation of cassiterite from primary tin ore (oxide and skarn samples) using gravity and magnetic separation.
2. Rock Gold Processing: On the other hand, processing rock gold begins with physically breaking down the ore by crushing it, sometimes in several steps, to get it ready for separating. Just like with alluvial gold, after we prepare it at the start, the ore taken from quartz veins or other hard rock spots goes through:
Tin ores that contain high sulphide mineral contents have to undergo an additional process, whereby the ore is baked at 500-600°C to burn the sulphur. Flotation is not as efficient for tin as it is for sulphide ores, it is becoming more frequently used to improve the amount of tin recovered from both primary ores and reprocessing to …

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.

Tin was found liberated as cassiterite in the secondary deposits, while in the primary, it was associated with other minerals requiring more complex processing. Therefore, a suitable technology is needed to extract the tin from the primary ore deposits.
The results were compared to the results obtained by artisanal processing techniques. The proposed mechanized techniques were found to increase the efficiency of tin and tantalum recovery from 60.75% to 81.85% and from 22.9% to 48.57%, respectively, and the grades of the tin and tantalum increased to 63.75% and 35.7%, respectively.
