Whereas, the contents of higher-MgO and lower-FeO than Ore-A leads to difficulty in melt generation. Thus, melt generation in saprolite Ni-ore occurs as the residual in the recrystallization ( i.e., formation of olivine) of non-stoichiometric serpentine, being enhanced by the amount of MgO leached and Fe 3+ by which Mg 2+ is emplaced in the ...
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.
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.
METHOD FOR NICKEL CONCENTRATION PROCESSING OF SAPROLITE ORE. 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 fine particles with middle specific gravity ...
In the Wingellina weathering profile (Fig. 2a, b), two main mineralisation styles occur: 1) oxide, and 2) saprolite ores.The oxide ore accounts for more than 75% of the Mining Reserves and consists of a reddish-to-brownish fine-grained oxy-hydroxide-dominated unit (Fig. 2c, d).Within the oxide ore type, two subtypes are recognized: i) a Fe-oxy-hydroxides …
Silicate type (or saprolite type) nickel ore formed beneath the limonite zone. It contains generally 1.5-2.5% nickel and consists largely of Mg-depleted serpentine in which nickel is incorporated. In pockets and fissures of the serpentinite rock green garnierite can be present in …

The present invention relates to a method for separating and sorting limonite ore and saprolite ore from nickel laterite ores. A method for separating and sorting laterite ores, according to the present invention, separates gangue, which exceeds a first particle size, and intermediate products of the first particle size or less from each other through particle size separation for …
The CNA Nickel is the fourth generation of the world's most advanced on-line elemental analyzer, based on the Pulsed Fast and Thermal Neutron Activation PFTNA technology. Nickel mining and extraction operations will benefit from control of quality and moisture of the ore before shipping to and arrival at the treatment plant, enabling sorting ...
To improve beneficiation of nickel and iron from low-grade saprolite laterite with 1.29 wt.%Ni and 16.31 wt.%Fe, co-reduction with limonitic laterite ore and basicity optimization were adopted as ...
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.

What I claim is: A method of recovering gold from auriferous saprolite ores which comprises cyaniding a pulp of the ore, treating the cyanided pulp with charcoal which has been preheated to about 1000° C. and subjecting the mixture to a froth flotation 4' process in the presence of a reagent favorable to the flotation of auriferous carbon.
Ore processing. The Ravensthorpe ore body is distinctive in that it has a high silica content, which enables the limonite ore to be upgraded to almost twice the mined grade through a beneficiation plant – a simple scrubbing and screening process to remove the barren, hard silica. The saprolite ore also upgrades but to a lesser extent.
Extraction and separation of nickel and cobalt from saprolite laterite ore were studied by using a method of microwave-assisted hydrothermal leaching and chemical deposition. The effects of leaching temperature and time on the extraction efficiencies of Ni2+ and Co2+ were investigated in detail under microwave conditions. It is shown that the extraction efficiencies of …
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.
PALAVRAS-CHAVE: Ore Sorting, Zinco, Pré-Concentração. ABSTRACT The natural decay in the average zinc content in the Vazante/MG mine sparked interest in the study of ways for economic use of marginal ores (between 3 and 4% of zinc). Ore Sorting was the technology chosen to pre-concentrate this poor ore fraction to enable its processing at
By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site.
