Over the years, alternative procedures to the Bond grindability test have been proposed
aiming to avoid the need for the standard mill or to reduce and simplify the grinding …

The depletion of high-grade ores has forced the utilization of low-grade ores. The small
liberation sizes in the low-grade ores require fine grinding which is an energy intensive …

The Bond work index (BWI) is a well-known method used when selecting comminution
equipment, to evaluate the grinding efficiency and to calculate the required grinding power …

Iron ores obtained from different sources differ in their chemical and physical properties.
These variations make the process of grinding a difficult task. The work carried out in this …

Nowadays, the demand for a finer grind in mineral processing has set new challenges within
the industry, particularly for grinding technology. Apart from a finer grind, energy efficiency is …

The present research aims to analyze the comminution behavior of ferrochrome slag using
high-pressure grinding rolls. The laboratory bench scale high-pressure grinding rolls were …

The run-of-mine extracted from the ground requires further processing in order to make a
marketable product. This preparation is called mineral processing. Thus, ores must go …

Grinding media influence the energy consumption and efficiency of the grinding process
during the calculation of the Bond Work index (BWi), a well-known method for selecting …

Banded hematite quartzite (BHQ) and banded hematite jasper (BHJ) ores represent a
promising potential iron ore resource in the near future. The hematite and quartz in BHQ and …

The bond index is an indicator of the grindability of the material and is widely used in the
preparation of mineral raw materials and the cement industry. Paper offers new, abbreviated …
