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
A method for separating nickel containing lateritic ore into limonite and saprolite fractions, the method including the steps of (a) providing said lateritic ore in particulate form (b) forming a slurry of said particulate ore (c) subjecting the ore slurry to a size separation procedure to separate the limonite and saprolite fractions on a selected threshold particle size basis

with the high intensity Induced Roll Magnetic Separator MIH 111-5 made by Carpco. 4. Mineralogy The nickeliferous ore deposit of the area is mainly ferrous and it constitutes of a lateritic crust weathered zone in contact with a saprolite zone in much smaller development. The ore sampling was held on the area of Kukes in Nome.
Jan 01, 2019 An ore sample (5 kg) containing both a fine iron hydroxide dominated fraction from the ferruginous saprolite, and rocky saprolite blocks from the saprolite horizon was investigated. In order to obtain representative samples, each 1 m fraction sample was first crushed down to 1020 mm.
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
High-grade saprolite ore has a nickel content of about 1.7% while mid-grade saprolite ore has a nickel content of between 1.3 to 1.6%. Most of our high-grade saprolite ore were sold to Pacific Metals Co., Ltd. (PAMCO), who use the material as feed for its ferronickel smelter. Our mid-grade saprolite ore were sold to Japanese and Chinese clients.
Jul 07, 2013 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
of saprolite ore and limonite samples shown on figure 3. Figure 3 is the relationship between the reduction temperature of saprolite samples at various variations of reduction time There is the influence of the amount of reducing agent on metallization of nickel at a reduction temperature at fixed temperature 900 C.

The first product of the separated granulation is classified as a saprolite ore to be used as a raw material of dry refining, and the fine-grain second product is classified as a
Sep 01, 2019 Nickel was upgraded in two samples of saprolite and the intermediate zones by gravity separation using the Falcon concentrator. The Ni grade increased by 17% and 36% for the saprolite and intermediate samples (i.e. ore S and I), respectively. The proportion of fine particles in the ores increases after gravity separation.
The lateritic nickel ore was low grade saprolite ore (LGSO) originating from Sulawesi Island, Indonesia. Before being used in the experiment, the saprolitic nickel laterite ore was dried at 135 C for 24 h, ground using a ball mill, and then sieved to obtain the grain size of
Feb 05, 2018 Method For Nickel Concentration Processing Of Saprolite Ore. ... methods used for early waste another significant difference is that the feed is introduced by gravity into the ore stage multi-separator as a dry product in a dsm cyclone the medium and the ore reports to a mixing box and nickel laterite.
A the saprolite frequently displays grayish colors. Weathered quartz veins in the saprolite are accompanied by red to orange iron oxides, the so-called Hunsrck ore, because the quartz veins were better aerated than the dense, loamy saprolite around them.
It is therefore required that separation of saprilite-type ore to use nickel laterite ore as a raw material for hydrometallurgy process. In this study, separation of sparolite-type ore and ...
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.
