The Jiaodong Peninsula hosts the main large gold deposits and was first production area in China; multisource multiscale geoscience datasets are available. is biggest drilling mineral-exploration zone China. This study used three-dimensional (3D) modeling, geology, ore body alteration to extract synthesize mineralization information analyze exploration targeting Zhaoxian deposit northwestern Pe...

Most of the world’s nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores ...

A fractal (power-law) distribution is the only statistical distribution applicable to a scale-invariant process. One of the major problems in petrology is the distribution of trace elements in the Earth’s crust. Extreme values of this distribution result in ore deposits. There is accumulating observational evidence that tonnage–grade statistics of ore deposits are often fractal (powerlaw). Rayl...

A three stage flotation scheme was employed to beneficiate a low grade. high dolomitic phosphate ore from Florida. The reagent scheme used. developed on the basis of our previous fundamental studies. consisted of oleic acid added as collector. mineral oil and ethoxylated sulfonate as co-collectors and 1. hydroxy ethylidene 1.1diphosphonic acid (Dequest 2010) as francolite depressant. The three ...

In Latin America, metallic ores are abundant and diverse. However, few metal-tolerant and metal hyperaccumulator plants have been reported in the region in comparison with other areas of the world. This may be largely explained by the scarcity of scientific studies of the native vegetation growing on natural mineralized or metal-contaminated areas and the unfrequent use of biogeochemical prospe...

Chlorite is the most common accessory mineral group found in high purity talc ore used in cosmetic or pharmaceutical consumer talcum products. X-ray diffraction and wet chemical analytical data obtained on geologic samples representing commercial talc ore deposits of high purity and on processed samples representing talc found in consumer talcum products indicate that clinochlore and penninite ...

Quality of ore varies in the complete spectrum of mining operations. Depending upon the quality control practices at mines, grade variation may follow a systematic pattern or an erratic fluctuation. The different statistical quality control techniques, especially control charts, are used for continuous monitoring of grade variation. The main purpose of the application of control charts is to id...
