20.1 Metal Deposits – Physical Geology

A magmatic deposit is one in which the metal concentration takes place primarily at the same time as the formation and emplacement of the magma. Most of the nickel mined in Canada comes from magmatic deposits such as those in Sudbury (Ontario), Thompson Get price

Metallurgical and Market Acceptance Test Work

Tests show that with further gravity processing using a Knelson concentrator, concentrate grades in excess of 15% nickel were achievable, with some subsequent loss in nickel recovery. During the 2011 exploration program at Decar, a 250-tonne bulk sample of mineralized host rock was collected from the surface of the Baptiste deposit. Get price

Reading: Ore Genesis

Iron ores are overwhelmingly derived from ancient sediments known as banded iron formations (BIFs). These sediments are composed of iron oxide minerals deposited on the sea floor. Particular environmental conditions are needed to transport enough iron in sea water to form these deposits, such as acidic and oxygen-poor atmospheres within the Proterozoic Era. Get price

- Iron is introduced into the laterite from outer sources (absolute iron accumulation). The difficulties of absolute iron accumulation on a larger scale were already discussed. Moreover, it is inexplicable that an introduction of iron is only active in lateritization of acidic and not of mafic and ultramafic rocks. Get price

Hydraulic Conductivity of Compacted Laterite Treated with

The objective of this study was to investigate the effect of iron ore tailings (IOT) on hydraulic conductivity of compacted laterite. The IOT conforms to ASTM C 618-15 Type F designations. In the present study, soil was admixed with 0#x2013;20#x25; IOT and compacted at moulding water content ranging from 10 to 25#x25; using four types of compactive efforts.

Deposit control agents that inhibit precipitation at dosages far below the stoichiometric level required for sequestration or chelation are called threshold inhibitors. These materials affect the kinetics of the nucleation and crystal growth of scale-forming salts, and permit supersaturation without scale formation. Get price

Currently, about 75% of the EU's chromium is being imported. In the value chain of stainless steel production, significant amounts of chromium are lost in ferrochromium (FeCr) slags and stainless steel (SS) slags. Get price

Geotechnical Properties of Mine Tailings

The specific gravity of the coarse and fine copper tailings are 2.77 and 2.76, respectively, which are smaller than those of the iron tailings but slightly larger than those of natural soils. Fig. 1 indicates that the mass percentage of grain size less than 0.075 mm is 14.9% for the coarse iron tailings, 78.4% for the fine iron tailings, 14.24% for the coarse copper tailings, and 61.12% for Get price

A Beneficiation Study on a Low Grade Iron Ore by Gravity

In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. The combination of spiral and multi gravity methods showed Get price
