This paper proposes a geostatistical approach for geological modelling and for validating an interpreted geological model, by identifying the areas of an ore deposit with a high probability of being misinterpreted, based on quantitative coregionalised covariates correlated with the geological categories. This proposal is presented through a case study of an iron ore deposit at a stage where the...

Alumina-rich iron ore is a widely existed polymetallic deposit in the nature, and it has a high comprehensive utilization value. Because the alumina and iron contents of alumina-rich iron ore vary from each other, there are many different measures and processes to recover iron and alumina from the various kinds of alumina-rich iron ore. In the blast furnace (BF) ironmaking process, the alumina ...

Indium (In) is commonly hosted in Sn-rich deposits but rarely reported in Sn-poor deposits. However, an In-rich and Sn-poor skarn deposit, the Qibaoshan Cu-Zn-Pb deposit, has been identified in south China. Geochemical analyses were undertaken on 23 samples representing the following mineral assemblages: sphalerite-pyrite, pyrite-chalcopyrite, pyrite-sphalerite-galena-chalcopyrite, pyrite, magn...

The article considers the geological features and ore composition of Dyusembay Central (Sayakhat) leadzinc deposit in Karsakpai metallogenic complex Kazakhstan. Historically, was considered industrially significant terms iron ores, rather than lead, zinc, copper. It is shown that composed tuffaceous, silty-sandstone, carbonaceous-terrigenous (ore-hosting), terrigenous, volcanogenic rocks assign...

It is shown that the giant Sikhote-Alin and Pamir deposits of boron are associated with fragments boron-bearing evaporite strata paleoceanic atolls in subduction melange. Ore formation relates both to situ transformation at Ak-Arkhar deposit mobilization redeposition some distance away from source course intensive post-accretionary fluid-magmatic reworking melange Dalnegorskoe deposit.

in this paper, iron ore sample from the chadormalu was investigated to determine some comminution properties. chadormalu deposit is one of the largest iron ore mine in iran, which is located in yazd province. the representative ore sample contained 57%fe, 0.9%p and 0.17%s. the sample was crushed; afterward, it was ground in various grinding times according to the bond ball mill approach to spec...

Research subject . The geological structure, petro-geochem ical features of the ore-bearing rocks Voznesenskoe gold ore deposit (Southern Urals) and geodynamic conditions its formation. Methods content petrogenic oxides was determined using silicate analysis; rare elements were determ ined ICP-MS methods by an EIAH 9000 mass spectrometer ICP-AES ICPE-9000 spectrometer. Results is confined to a ...

A study on the quantitative leaching of iron ore in hydrochloric acid solution has been undertaken. The elemental composition of the iron ore was also carried out using ICP-MS technique. The major elements in the iron ore include: Fe(66.7%); Al (0.2%); Si (5.2%); Ti (0.02%) and O (28.0%). Some traces of V, Ni, Zn, Ce, Cr, La, Y and Zr were also found. The effects of contact time, acid concentra...
