The addition of 0.5% Nb in the steel led to the formation of the Laves phase.This phase, associated with the sigma phase, increases the hardness of the steel,

The energy speciic selection func- tion and the breakage function were used in the simulator to predict the behavior of the industrial circuit oper- ated with 23.3%

However, at a mold extraction rate of 80 µm/s, the grain structure consisted of columnar grains aligned in the radial direction and SiC particles were observed throughout the

The objective of this work was to study the new occurrences of bentonite clays in the municipality of Pedra Lavrada, state of Paraíba, Brazil, for use in water based

The DCP penetrometer (Dynamic Cone Penetrometer) was introduced as an alternate test device for the compac- tion control of tailings dams raised by the upstream

The best option to concentrate the iron from the slime thickener is to adopt the equipment similar to W2 in the rough- er step with a ield intensity of 1.2 T, mass concentration

In one series of blast tests, blast- ing costs per unit volume of rock were reduced to 16% by increasing burden and spacing distances (Cevizci, 2012).

Thus, in order to ensure a sustainable sequence of operations, and to predict the environmental impacts caused by mining activities and suggest options that would allow the
