density channel iron deposit

Rapid electrodeposition of iron from ferrous chloride baths

soft, ductile deposits can be produced from concentrated solutions of nickel sulphate (4 N), at a low pH (pH=l), a high temperature (1000 C), and current densities up to 30 amp/dm2 (280 amp/ft2), which is about 15 times the current density regularly employed for this process.

Channel-iron_deposits

Channel iron deposits, also known as pisolitic iron ore are a major source of cheap, high grade iron ore exploited primarily in the Pilbara and Murchison regions of Western Australia.. The ore bodies consist of nodules of hematite, limonite-goethite with some clay, sand and silt matrix. These nodules (pisolites) are concentrated into alluvial and elluvial washes leading from the source regions ...

Appendix 1 Executive Summary

On the northern margin of the Archean Pilbara Craton, in the Northeast Pilbara (Figure 3) the Nimingarra Iron Formation (NIM) hosts the Yarrie-Nimingarra iron ore deposits. Another important iron bearing sequence is the Marillana Formation which is a detrital derived Channel Iron Deposit (CID) of late Eocene to Early Miocene age.

Understanding porosity and density

Porosity measurements of Wisconsin rocks. The porosities of the rocks measured vary from 2% to more than 30%.Much of this variation is due to lithology (rock type). The data table lists the porosities of the tested samples and the figure at right shows the range and distribution of porosities by lithology. The dolomites have the lowest porosities (2–6%), the shales have the widest range of ...

Heavy Metals Toxicity and the Environment

Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological applications have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environment.

Abstract: Fine iron ore tailings slurry is commonly deposited in tailings storage facilities across the Pilbara region of Western Australia. Many of these mines process ore from a combination of deposits such as Bedded Iron Deposits (BID), Channel Iron Deposits (CID) and Detrital Iron Deposits (DID), mixing the feed to obtain the product under contract.

IRON-NICKEL (Fe-Ni)

Native Iron is quite often a misnomer as natural iron is not necessarily "native" to Earth since it rarely occurs on the Earth''s surface by terrestrial processes. It is mostly found in the form of meteorites that have impacted the Earth''s surface. A few rare terrestrial gabbros and sulfide deposits do contain elemental iron-nickel deposits, these are the only truly native iron-nickel.
