Did you ever wonder how ore sorting works?  Let's delve into the fascinating techniques used in this process! 

Optical sorting: This technique relies on sensors to identify differences in the optical properties of ores. It uses cameras or lasers to analyze size, shape, color, and lusters, enabling the system to separate valuable ore from waste efficiently. 

X-ray transmission: X-ray technology is used to determine the atomic density of each particle to distinguish between low-density waste and high-density valuable ore. This technique is often employed to sort minerals like gold,copper, coal, and other dense materials. 

Magnetic separation: As the name suggests, this technique uses magnets to separate magnetic materials from non-magnetic ones.This method is commonly used in iron ore processing to remove unwanted magnetic material and produce a concentrate of higher iron grades. 

Gravity separation: Based on the principle that different materials have different densities, gravity separation techniques use centrifugal force or water flow to separate valuable ore from gangue (waste). It's widely utilized in mining operations to separate gold, tin, and other heavy minerals. 

These techniques are revolutionizing the mining industry by improving both efficiency and sustainability.
