Grinding

Grinding

Grinding equipment for mineral processing. The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the ...

for cyanide control at Ergo has been one of leach/cost optimization. However, more recently, with the increased public awareness of cyanide in the environment, a secondary but increasingly important motivation for control has been to ensure that only the minimum amount of cyanide is added to the process whilst not compromising leach performance.

SAG Mill Optimization using Model Predictive Control

SAG Mill Optimization using Model Predictive Control

Mineral processing operations present many challenges for automatic process control due to variations in unmeasured ore properties, material transport delays, and nonlinear response characteristics. Control of SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects.

 · The process of enriching taconite ore involved grinding the ore to remove gangues and upgrading the iron ore (, an ore beneficiation process). The resultant high grade ore is in the form of fine particles, as small as mm or less, which are not suitable for sintering. This issue led to the development of the pelletizing process.

Grinding is a significant and critical part of the ore winning process. On average, milling is the process that requires the most energy in the whole mining operation. To ensure profitable operations, an efficient grinding circuit has to be designed, especially now, where global mineral resources are decreasing and the exploitation of lowgrade deposits become necessary.
