Proper quantification of the abrasiveness of different ores may be based on standardized tests. Such quantification in the mining industry is usually made through the Bond [1] test method, the preferred alternative among the various abrasion tests avail-able [2,4–7,11]. The outcome of this test is the Bond abrasion index (Bond Ai), which finds

A fourth index attributed to Bond is the abrasion index (Ai) which is used to predict the quantity of liner and ball wear in classical comminution equipment. One complication to comparing parameters is …
CIL circuit is a process of continuous leaching of gold from ore to liquid and counter-current adsorption of gold from liquid to carbon particles in a series of tanks. The CIL process concentrates gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t on carbon. Although the earliest process was in South Africa in 1890, CIP/CIL was first introduced ...
Compare and Understand Rod/Ball/Impact-Crushing/Abrasion BOND Work Index
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
This characteristic of ball media wear rate vs the bond index was investigate at part of the AMIRA P9L project 1996-1999. It was found the systems dominated by corrosive wear mechanisms (ie: mild steel media) had wear rate in the 100-159g/kwh range and the systems that did not have corrosive wear mechanisms (Cr media or non-corrosive ores) …

*Mines with equal capacities have the same rankings. †2020. The ndida Mine in Chile is by far the world's largest copper mine. Its annual capacity of 1.4 million tonnes means that it can produce more copper than the second and third-largest mines combined.. Porphyry copper deposits are often characterized by lower grade …
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear …
The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills.
