SAG mills are primarily used at gold copper and platinum mines with applications also in the lead zinc silver alumina and nickel industries The largest SAG mill is 42 in diameter powered by a 28 MW 38 000 HP motor AUTOGENOUS GRINDING MILL SAG They are so called due to the self grinding of the ore A rotating drum throws larger rocks of ore in a cascading motion It causes
Both ore types can be economically mined but they are processed in different ways Copper sulfide ores are typically the most profitable copper ore type to
Spica Part 2 In the last issue of Copper we briefly looked at loudspeaker manufacturer Spica the company s founder John Bau and the company s speakers which are still used and revered by many decades after the company s demise Luckily founder/designer Bau is still alive and well; I spoke at length with John on February 7th 2021
The mine planning process is complex and integrates several technical branches of the mining Circuit Example and Copper Zinc Circuit Example Grinding 1 Fundamentals > This course is the first of a suite of three courses on grinding engineering from Metso Performance Solutions covering Mineral Processing Basics
Sulphide copper gold ores are usually sorted by flotation The standard comminution process to grind the ore to flotation fineness mostly consists of coarse crushing followed by SAG milling or wet ball mill circuits or alternatively multiple stage crushing followed by rod and ball milling The two most common compressive comminution technologies are the high pressure grinding roller HPGR
Grinding the final stage used in the comminution process is usually conducted in cylindrical tumbling mills where the particle size is reduced through a combination of impact and abrasion The primary differences between these mills are in the ratio of diameter to the length of the cylinder and the type of grinding media employed Grinding media can be steel rods steel balls hard pebbles
