Platinum, palladium and gold leaching from magnetite ore

Dec 01, 2016· Additionally, it could be established that the ore sample is composed mainly of magnetite in the presence of other metals and crystalline phases. Platinum and palladium can be present as iron “micro-alloys” type [Pt-Pd] x Fe y (Maier et al., 2003, Stone, 1990). No detailed mineralogy of the PGM-containing phases was undertaken in this study

Platinum, palladium and gold leaching from magnetite ore

A leaching process for platinum contained in a magnetite ore was studied, as an alternative process to cyanidation and aqua regia digestion. The proposed process employs concentrated chloride solutions and ozone gas injection during the entire leaching process. The effect of pH, chloride concentration and temperature was analyzed.

Magnetite Mineral Physical Optical Properties

Apr 26, 2018· Magnetite is a common ore of iron. It is found disseminated as an accessory mineral through most igneous rocks. It is found disseminated as an accessory mineral through most igneous rocks. In certain types through magmatic segregation becomes one of the chief constituents, and may thus form large ore bodies.

Yellow Banks Placer Near La Push, Washington The Diggings™

The Yellow Banks Placer is a placer mining operation. Initial production took place in 1900 and overall output was considered to be small size. The ore mined is composed of gold, magnetite and platinum. The ore is stratabound of unknown dimensions. The host rock in this area is sand & gravel from the Holocene epoch 11,784 years ago to present.

Platinum Earth Sciences Museum University of Waterloo

Smaller reserves can be found in the United States, Zimbabwe and Australia. Platinum is also attained through recycling. For example, in 1999 70 metric tons were recovered in this way. Sperrylite: Platinum arsenide, or sperrylite, is the only platinum ore of any significance besides native platinum.

DF2014:Magnetite Dwarf Fortress Wiki

Magnetite is an ore of iron.It appears as large, oval-shaped clusters inside sedimentary layers.A magnetite cluster may sometimes contain veins of native platinum, which can continue outside of the cluster itself.. In terms of metalsmithing, magnetite is identical to hematite and limonite.However, magnetite is distinguished by the extreme size of each deposit compared to the other iron ores

Bushveld Igneous Complex Wikipedia

The Bushveld Igneous Complex (BIC) is the largest layered igneous intrusion within the Earth's crust. It has been tilted and eroded forming the outcrops around what appears to be the edge of a great geological basin: the Transvaal Basin.It is approximately 2 billion years old and is divided into four different limbs: the northern, southern, eastern, and western limbs.

Coal Washing, Magnetic Separation & Processing

In comparison magnetite ore has lower iron content when mined of between 25% and 40% Fe and requires processing, or magnetic separation, to separate magnetic minerals from other minerals in the ore. The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3O4) which when processed produces a magnetite concentrate with a
