Ball mill is a more commonly used and efficient grinding equipment. It is suitable for grinding ore such as iron ore, gold ore, copper ore and leadzinc ore and other metal beneficiation, used to grind the ore below for subsequent beneficiation process. According to different discharge methods, it can be divided into grid type and ...

This study investigated ultrafine coal grinding performance of four low to moderatecost grinding media in a laboratory stirred mill. Kinetic grinding tests showed that silica beads generated the finest product size with a P 80 of μm from a feed size of μm while having a specific energy (SE) input of 309 kWh/ton. Nonetheless, the least energy consumption of 109 kWh/ton was ...

The Century concentrator is primarily a conventional grinding and froth flotation circuit, comprising one SAG Mill, two ball mills, 21 stirred mills and 79 flotation cells. Due to the particularly fine nature of the zinc in Century's ore, and its silicate content, the ore must be ground using an ultrafine grinding process.

Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large stratabound Mississippi ValleyType (MVT) ore deposits of base metals such as lead, zinc, and copper.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

The ability to grind ore down to sizes below 10μm has lead to the establishment of new mines such as McArthur River, Century and George Fisher mines, as well as improving recoveries of lead and zinc at the established Mount Isa deposits. Fine grinding has also opened up the door to new leaching processes.
