Depending on the ore from which nickel is obtained, some of the slags produced can also be enriched in other metals such as copper, which may also be extracted as a valuable commodity. Kalinkin et al. 76 produced alkali-activated binders based on Cu–Ni slags from such a process, and found that grinding of the slags increased their reactivity ...

1 Froth Flotation – Fundamental Principles

This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.

Finding the ideal materials for gears | Gear Solutions ...

The most common stainless steel is 304 alloy. It contains 18% chromium and 8% nickel. For gearing, 303 stainless is typically used. In 303 alloy, the chromium content is reduced to 17%, and 1% of the alloy is sulfur. Because of the addition of the sulfur, 303 alloy has improved machinability compared to 304 alloy.

nickel improves film resistance in some acid environments. Material Selection Many variables characterize a corro-sive environment – i.e., chemicals and their concentration, atmospheric condi-tions, temperature, time – so it is difficult to select which alloy to use without knowing the exact nature of the environment. However, there are
