isamill in gold milling

IsaMill™ Glencore

IsaMill™ uses horizontal milling to secure better energy efficiency, product size and availability The IsaMill™ has real-world success in 143 metalliferous installations across 23 countries. It’s the world’s only The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill. The mixing chamber is filled with the grinding medium (normalIsaMill

Many have followed since then, with Anglo Platinum being the champion in the industry with five IsaMills currently running on Keramax® MT1TM and another 16 due to be commissioned over the coming 12 months. Ceramic grinding media Varied types/geometries of stirred mills have been produced by different manufacturers, and the comparison task has been accomplished for some of the technologies, i.e., Tower mill vs IsaMill. However, the main drawbacks of these comparisons were the uncommon characteristics of the milling environment, such as media size. In Minerals Free Full-Text Performance Comparison of the MDPI

Comparison of energy efficiency between ball mills and stirred

Open circuit batch ball mill compared with laboratory IsaMill to grind a feed of top size around 1 mm to a product P 80 less than 100 μm (Burns, 2007). • Full scale regrind ball mill in closed circuit compared with full scale IsaMill in open circuit to grind a feed of top size around 150 μm to a product P 80 less than 65 μm (Pease et alincrease the pre-aeration time needed. In a recent application of the Isamill, the existing regrind mill before gold leaching was consuming 10 t/day of steel balls. This reduced pulp Eh and extended residence time in subsequent pre-aeration and increased cyanide consumption in leaching. Three mechanisms are important when fine grinding beforeFine Grinding as Enabling Technology The IsaMill

Effects of disc rotation speed and media loading on particle flow

IsaMill™ is a high-speed stirred mill used in the mineral industry for a range of milling duties from ultra-fine to coarse grinding. In this work, numerical simulations based on the discrete element method (DEM) were performed to investigate the particle flow in a dry stirred mill with a similar configuration to that of an IsaMill™. ™. The effects of 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 Energy Use of Fine Grinding in Mineral Processing SpringerLink

Regrind Mills: Challenges of Scaleup Abstract 911 Metallurgist

The scaleup procedures developed for the IsaMill were then compared against the full scale Century SMD’s. The IsaMill M4 procedure accurately predicted the full scale Century performance on a P 80 basis. This is intuitively correct though the mills have different designs (horizontal versus vertical), essentially –a refractory gold/silver concentrate, producing 80,000 ounces of gold annually.
