2, that contains 50%w/w of ser- pentinite, presents a Strength (kgf/pellet) near the one obtained in test 1, containing only bentonite, with a strength reduction.. ) tumbles of

The proposed indexes (CDI – Cold Disintegration Index, DI – De- crepitation Index, and HDI – Heating Disintegration Index) are eficient for the quantitative

of the heating rate on the kinetics austenite formation in the continuous heating of low carbon steel with initial microstructures composed of ferrite and pearlite,

Equation (8) provides a mathematical expression for the variation of the organic matter concentration with time as a func- tion of the complexation "equilibrium"

The printed circuit boards (PCB) represent approximately 30% of the electronic waste generated and its recycling is a complex process, but very important for the recovery of metals

(2001) discuss the occurrence of toppling and buckling lexural mechanisms in foliated rock masses, focusing their occurrence in slope mines (see Figure 2).. Based on

The present study compares the action of the main frothers in terms of: mean bubble size in the pulp zone, froth stability, surface- tension-lowering ability and reagent

The main management challenges are to: (i) act in a vari- ety of environments and conditions based on action priorities; (ii) identify the main company’s image risks;
