NovaCell can drastically reduce the mining industry s energy and water consumption and greenhouse gas emissions world-wide. The NovaCell process can reduce energy costs in a typical base metal mill by 40 . This translates to 10 of the total operating cost of a mine that produces a metal like copper zinc or nickel.

Optimization of a SAG Mill Energy System Integrating Rock
An optimization is carried out to minimize the yearly cost of energy for the operation of the SAG mill. This cost includes the energy consumption cost in /kWh and the capital cost for the PV-BESS infrastructure prorated over the life of the battery system accounting for the discount rate through an annuity factor (Pamparana et al. 2019a b).The energy requirements are defined by the SAG

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.

SAG mills rod mills and ball mills are the classical pieces of grinding equipment employed in gold recovery plants. There is an increasing trend to employ SAG mills (semiautogenous mills) in place of secondary and tertiary crushing and primary grinding. The most common type of rod mill is the overflow mill. There are two typed of ball mills used.

Energy Use of Fine Grinding in Mineral Processing
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.
