gomish-tappeh zn-pb-cu (ag) deposit is located 90 km southwest of zanjan, in northwestern part of urumieh-dokhtar volcano-plutonic zone. exposed rocks at the area include oligo-miocene volcano-sedimentary and sedimentary sequences as well as pliocene volcano-plutonic sequence (andesite porphyry dykes, dacitic subvolcanic dome and rhyodacitic volcanics). alteration in the deposit developed as si...

Here, we report the draft genome sequence of the betaproteobacterium Ideonella sp. strain A_228. This isolate, obtained from a bog iron ore-containing floodplain area in Germany, provides valuable information about the genetic diversity of neutrophilic iron-depositing bacteria. The Illumina NextSeq technique was used to sequence the draft genome sequence of the strain.

The impact behavior between the charge and lifter has significant effect to address the mill processing, and is affected by various factors including mill speed, mill filling, lifter height and media shape. To investigate the multi-body impact load behavior, a series of experiments and Discrete Element Method (DEM) simulations were performed on a laboratory-scale mill, in order to improve the g...

This paper presents the mineralogy and chemical composition including iron ore impurities to ascertain its suitability for industrial applications. The Asanje deposit is hosted in Precambrian volcano-sedimentary rocks Mayamaya-Hombolo Belt Dodoma region, within Lake Nyanza Superterrane. Iron ores are found two parallel ridges trending NW-SE. Ridge I occurs as vein banded hematite-type II massiv...

The production and trade of metals was the foundation economic wealth many regions in world, which makes study ancient metallurgical slags primary importance. This type is relatively new for Bulgaria, where research field started late 1960s with chemical analysis copper ore, slags, tools finished goods from mine Ay-bunar area. Iron one most commonly found elements earth’s crust its deposits are...

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...
