Four of the six holes completed contain nickel intercepts of 0.20% to 0.24% total Ni with included sulphide nickel at 0.10% to 0.15% Ni respectively. A key factor in making the Kilometer 26 project concept feasible is the virtual absence of non-nickel bearing sulphides which if present would dilute the resulting sulphide concentrate.

Grade 5 alloy steel is a medium carbon zinc plated alloy steel that is heat treated to increase hardness. Grade 5 bolts have three (3) evenly spaced hash marks on the head markings (manufacturers mark may also be included). Grade 8 / Grade G. Grade 8 zinc plated alloy steel bolts are thru-heated and thru-hardened with a CR+5 zinc plating.

The results of these tests were released to the market in August 2016 for a 0.7% nickel grade (calculated as an average of recoveries from 0.6% Ni and 0.8% Ni) and are compared to the Gipronickel results for the half tonne bulk sample (actually 443.9kg), which had an actual nickel grade of 0.7% (see Exhibit 12, below).

head grade of 0.25% nickel and fine flotation tailings retrieved from dump with a head grade of 0.15% nickel obtained from a nickel mine. The materials were ground to 65% < 75 µm in a laboratory rod mill before being leached. while concentrate grade is 9%. The concentrate is toll smelted . Leaching of tailings in strong acids at room temperature

Head grade - The average grade of ore fed into a mill. Heap leaching - A process whereby valuable metals, usually gold and silver, are leached from a heap, or pad, of crushed ore by leaching solutions percolating down through the heap and collected from a sloping, impermeable liner below the pad.

Mineralogy limits concentrate grade to 7–8% Ni and 5–6% Cu. Pyrite contains little nickel but its recovery to concentrate is far greater than other minerals at 93.5%. Under recent production conditions at 0.48% Ni head, concentrate mass is 6.82% at 5.80% Ni and 81.8% recovery.

Grade 5 Bolts are equivalent to Metric 8.8 bolts, so when finding the right bolt, be sure to match the grades on the bolts being used. Grade 5 bolts can often be identified by the 3 marks on the head. Each Grade 5 bolt from U-Bolt-It are available zinc plated. Have a question about our manufactured grade 5 bolts?

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.

Concentrates grading between 13.4 and 13.8% nickel were produced with nickel recoveries ranging between 86.0% and 87.3%. Copper recovery to concentrate was very high averaging 94%. Iron to MgO ratios were 5.9:1 and 6.9:1 respectively for MC-1 and MC-2 representing MgO grades of 3.2% and 3.9% for the two master composites.

Approximately one-third of the mined ore (2.2Mt) is transported by road trains to the concentrator at SMC, which operates a single semi-autogenous grinding mill (SAG), while the rest is transported by overland conveyor system to the crusher and ball mill concentrator modules at …

Nickel mining and smelting operations in New Caledonia. In 2005 with the world facing an impending shortage of nickel required to feed Chinese industrialisation the Chinese adapted old decommissioned technology (pig iron blast furnaces) to treat nickel bearing iron ore (laterite) and produce very low grade FeNi (2% Ni).

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.

due to its notorious micro-gabbro nickel ore reducing the availability and throughput of the crushing circuit. A new mine plan was adopted which extended the life of mine by reducing the cut-off grade, but had the consequence of requiring the concentrator to treat additional ore with a lower head grade.

Based on a long-term nickel price of US$7.17/lb (cf a spot price of US$5.88/lb at the time of writing), we calculate an 8c/share valuation based on the net present value of the (fully diluted) stream of dividends that results from the proposed toll smelting development of Kun-Manie in FY19 (using a 10% discount rate) and a 12c/share valuation from the low-grade matte option.

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.

Most offer good weldability and formability in comparison to other families of steel. Some are offer improved corrosion resistance. Chloride-resistant stainless steels are especially popular in offshore use. Common duplex alloys include are 318L, LDX 2101, LDX 2304, 2507 and 4501 (Also known as 25CR superduplex) grades.

This tells us that the concentrate has 9.57 times the copper concentration of the feed. 1.1.1 Grade/Recovery Curves While each of these single calculated values are useful for comparing flotation performance for different conditions, it is most useful to consider both the grade and the recovery simultaneously, using a "Grade/Recovery Curve".
