Use of drilling performance to improve rock-breakage efficiencies: …
Processed MWD data can be used to predict the rock-breakage efficiencies in crushing and grinding processes based on the relationship between drilling performance (APR) and intact rock properties. A series of laboratory rock tests–drilling tests using a high-precision coring machine, tensile tests, and BWI tests–were conducted to find the ...

(PDF) The Effects of Blasting on Crushing and Grinding Efficiency and
Drilling and blasting are fundamental operations in the mining cycle and constitute an important component of the mining costs. Rock fragmentation can in principle be managed by means of two options: by increasing or reducing the specific consumption of explosives, or by modifying the drilling pattern.

Comminution and classification technologies of iron ore
Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.

Energy Use of Fine Grinding in Mineral Processing | SpringerLink
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 …
