Dec 18, 2013· 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.

The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation.
We have designed the largest installation base of advanced control (expert systems) for comminution circuits in the world. Our reference list speaks to our global experience and includes grinding circuits, both large and small, including the largest operating grinding circuit in the world – Collahuasi Rosario''s 40foot SAG mill.
The Coalition for Energy Efficient Comminution (CEEC) has been established and is supported by a broad range of mining sector companies keen to accelerate awareness, knowledge transfer and, by implication, improve energy and cost outcomes in the substantive area of comminution.
Conversely, finegrained magnetite ores require fine grinding, often to below 30 μm, to liberate the magnetite from the silica matrix, incurring greater costs and energy consumption. The comminution energy consumption could be over 30 kWh/t, an order of magnitude higher than for hematite ores.
Various types of equipment are used for comminution. Crushers are used in the coarse size region, while grinding mills serve for preparing fine products. Comminution processes are generally preliminary to the separation processes. To avoid excessive cost for grinding and/or disadvant ages caused by overgrinding, however, some

Continuous grinding, as shown in Figs (b) and (c), is needed in massproduction environments like the cement industry, whilst batchwise processes, as shown in Fig. (a), are used for the smallscale production of highpurity products such as those used in the manufacture of elec tronics components.
Feb 24, 2015· A significant fraction of iron ore used in steel production comes from magnetite deposits. Magnetite iron ore requires significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. And grinding consumes a lot of energy. This article investigates ecoefficient alternatives for the process design for magnetite iron ore.
MIG or mainstream inert grinding—so named to indicate the ''mainstream'' application in the process flow, the target grinds are typically 80%–45 microns at the finest level and the ''inert'' or non steel media ''grinding'' environment UFG or ultra fine grinding—the conventional mining industry term for

Historically, the lowest operating cost was achieved by multistage fully autogenous grinding with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation.

Processing of Magnetite Iron Ores Comparing Grinding . The Coalition for Energy Efficient Comminution CEEC Processing of Magnetite Iron Ores Comparing Grinding Options Although the majority of current steel production is supported by iron ore sourced from high grade haemetite deposits the longterm growing demand for steel has led to higher raw material prices and opened the way for .
Relationships between comminution energy and product size for a magnetite ore [4] where E is the net specific energy; x f and x p are the feed and product size indices, respectively, and K3 is a constant. Hukki (1962) evaluated these energysize relationships
In this study, a magnetiterich ore was comminuted using laboratoryscale SFC and HPGR in opencircuit operations. Both comminution devices were operated at an identical net specific energy input, and their respective particle reduction ratios, sizespecific energies (SSEs), and Bond operating work indices were used to evaluate and compare their grinding efficiencies.
Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "runofmine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material.
Although the majority of current steel production is supported by iron ore sourced from highgrade haematite deposits, the longterm growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed. There is a rich and long history of magnetite ore processing in...
