In addition to his reply i can back that up with pictures and or user references. Also in the past sonic was limited to unconsolidated and wet materials however time didn't stood still and the new sonic dual wall core barrel and sonic wire line developments allow to sample even in granite, dry ore bodies or saprolite nickel stock pile material with 99% recovery.
A process for the recovery of nickel and/or cobalt from a lateritic ore by heap leaching, the process including the steps of : a) forming one or more heaps from a lateritic ore body wherein that lateritic ore body includes a blend of both limonitic and saprolitic type ores; b) leaching the one or more heaps with a leach solution; and c) recovering the nickel and/or cobalt from the resultant ...

Nickel laterite ore is used to produce nickel metal, predominantly to manufacture stainless steel as well as nickel sulfate, a key ingredient in the batteries that drive electric vehicles. Nickel laterite production is on the rise and surpassing conventional sulfide deposits. The efficiency of mining and processing nickel laterites is defined by their mineralogical composition.

The biggest differences were found in grain size, sorting, surface texture, shape and composition between the residual materials (saprolite, mottled clays and iron crust) and the transported materials (pisolitic gravel, yellow latosol and alluvial deposits). The soil and the gravels have the lowest size-sorting values of all levels in the profile.
ASX-listed Northern Minerals has progressed its potentially game changing ore sorting initiative with the successful testing of the sorter system at its Browns Range rare earths pilot operation in the north of WA. The company is now producing sorted material and converting this to a 30 percent total rare earth oxide concentrate at its Browns Range pilot beneficiation plant in the north of WA.
The extraction and separation flowchart of the saprolite laterite ore is presented in Fig. 2. All the experiments were conducted in duplicate to assure that the whole procedure was accurate. Seven ...
Nickel is apparently enriched in both saprolite and rocky saprolite, but cobalt is only enriched in the saprolite. The principal ore minerals identified in the Ramu deposit include goethite, asbolan and garnierite. Goethite is found as ochre-coloured, porous, cryptocrystalline, needle-like matrix in the limonite and saprolite zones of the laterite.
Typical nickel laterite ore deposits are very large tonget price.Nickel Ore Gravity Concentration Plant From the above, because nickel concentration is observed in a saprolite ore, on (a) rough particles with low specific gravity, that is, having a particle size width of 25 to 75 mm, and a specific gravity of equal to or smaller than 2.0, (b ...

The present invention relates to a method for mutually separating and selecting limonite and saprolite ores from nickel laterite ores. According to the present invention, the separation method of laterite ores comprises the following steps: separating gangue having a grain size of greater than a first grain size and an intermediate product having a grain size of less than or equal to a second ...
Nickel laterite ore is classified into two principal ore types: saprolite (silicate ore) and limonite (oxide ore). Saprolite-type ore characterized by high magnesia and silica contents is treated by pyrometallurgy process. On the other hand, limonite-type ore is subjected to hydrometallurgy process to produce nickel products. Hydrometallurgy process requires that a raw material to meet the ...
Abstract. Pedoplasmation is the process of transformation of saprolitic material to soil parent material. It is defined as the in situ development of a structured, loose material, in which the original fabric of the saprolite or sediment from which it is derived is no longer visible. Although first considered as an isochemical and isomineral process, physicochemical and micromorphological data ...

The proposed Project would involve extraction of gold ore from the Golden Ridge and Kenbert Concession areas located in the Birim North District (Figure 2-1). Current reserves associated with the Project are estimated at 116 million metric tonnes of ore containing approximately 7.7 million ounces of gold. On completion of mining, the
For ore containing over 1.5% nickel and 15% to 20% iron (known as saprolite ore), prices have fallen from well over US$100 per tonne in early 2014 to …
Eagle Mountain Saprolite Gold Project is a low-cost gold mine located within the 5,050ha Eagle Mountain Prospecting Licence (EMPL), approximately 230km south-west of the Georgetown, Guyana, South America. Goldsource Mines (Goldsource), through its Guyanese subsidiary Stronghold Guyana, holds interest in the gold deposit.

Ore sorting has significant benefits as it means rejecting waste before the plant, resulting in a higher grade lower volume feed to the plant, and, as Coringa will have filtration and dry stacking of tailings instead of a tailings dam, reduced levels of tailings. ... "saprolite" ...
The produced matte is then purified through either hydrometallurgical or pyrometallurgical processes to produce high-purity nickel. In general, this process for sulfide ore has been known as a more cost-effective process than that for oxide ore.The oxide ore is laterite comprised of two different ore types, saprolite and limonite.

Saprolite (from Greek σαπρος = putrid + λιθος = rock) is a chemically weathered rock (literally, it means "rotten rock"). More intense weathering results in a continuous transition from saprolite to laterite.. Saprolites form in the lower zones of soil horizons and represent deep weathering of the bedrock surface. In lateritic regoliths – regoliths are the loose layer of rocks ...

In the saprolite containing only traces or local parts of kaolinite, the dominating group of layer minerals are nickel-bearing serpentines beside some talc, chlorites and smectites. In the saprolite phyllosilicates represent the most important Ni-ore with a Ni-content rising to 2 to 3%.
