AL-6XN ® alloy (UNS N08367) is a low carbon, high purity, nitrogen-bearing "super-austenitic" stainless alloy. The AL-6XN alloy was designed to be a seawater resistant material and has since been demonstrated to be resistant to a broad range of very corrosive environments. The high strength and corrosion resistance of the AL6XN alloy make it a ...

In this case the maximum grade of Cu is restricted by the host mineral, hence to chalcopyrite the Cu grade cannot exceed 34.63% in the concentrate, even assuming recovery of chalcopyrite. This is a simply a function of the chemical composition of chalcopyrite with 34.63% Cu, 30.42% Fe and 34.94% S.

Type 304—the most common grade; the classic 18/8 stainless steel. Outside of the US it is commonly known as "A2 stainless steel", in accordance with ISO 3506 (not to be confused with A2 tool steel).[6] Type 304L—same as the 304 grade but lower carbon content to increase weldability. Is slightly weaker than 304.

The sample selected for testing was a pentlandite dominant sample with a nickel head grade of 0.35%, an iron head grade of 6.0% and a sulphur to nickel ratio of 1.1. This sample was selected because it is a representative sample of what is expected to be processed in Phase 1 of mill operation.

Hastelloy C276 ® is also specified in sour gas applications (NACE MR0175) and is commonly used in Flue Gas Desulfurization (FGD) applications for scrubbers, dampers and ducts. Hastelloy C276® - UNS N10276. Werkstoff Nr. 2.4819. Common Trade Names: Hastelloy C276®, Nickelvac® HC-276, Inconel® 276, Nicrofer® 5716.

This concentrate is therefore very low grade, from the milling point of view, running only 77.6% of perfect grade. On the other hand, the low sulphur assay of concentrate B shows this to be a marmatite, for 10% iron occurs in the form of FeS and only 2.5% iron as pyrite.

1 Poseidon Nickel (ASX:POS) revealed today that progress so far on its 'Fill the Mill" strategy supports fast tracking several initiatives for the restart of the Black Swan nickel operation in Western Australia. The news comes just a day after the company reported "exceptionally high-grade" intercepts from drilling into the Tundra-Mute ...

Nickel recovery vs. MgO rejection: treated (approaches 1 and 2) vs. untreated ore. The main gangue contaminant in the concentrate was pyrrhotite (Po) as indicated in the XRD pattern ( Fig. 6 ). From the Fe assay and assuming no other Fe-bearing mineral in the concentrate besides pentlandite, the pyrrhotite content at 80% Ni recovery was ca. 30%.
