Variability Study of Bond Work Index and Grindability Index on Various Critical Metal Ores [PDF]
Metals, 2021 It is a well-known fact that the value of the Bond work index (wi) for a given ore varies along with the grinding size. In this study, a variability bysis is carried out with the Bond standard grindability tests on different critical metal ores (W, Ta ...

Stable Weak Approximation at Work in Index-Linked Catastrophe Bond Pricing [PDF]
Risks, 2017 We consider the subject of approximating tail probabilities in the general compound renewal process framework, where severity data are assumed to follow a heavy-tailed law (in that only the first moment is assumed to exist). By using the weak convergence

EFEITO DO ESCALPE NO WORK INDEX DE BOND
Holos, 2015 O parâmetro mais amplamente utilizado no dimensionamento de moinhos é o WI de Bond. Contudo, dependendo das características físicas do minério nem sempre é possível determina-lo de forma adequada.

Heating Pre-Treatment of Copper Ores and Its Effects on the Bond Work Index
Minerals (Basel, Switzerland), 2022 Comminution is the stage with the largest energy consumption in the mining process. Therefore, several pre-treatments have been proposed to reduce the energy requirements of this stage. This work analyzed the effect of a heating pre-treatment on the Bond index. A conventional heating pre-treatment was applied to a Chilean copper ore. The ore was heated
