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...

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.

Iron is one of the most important strategic materials in national production, and demand for iron ore huge world. High quality reserves have been almost exhausted, it necessary to develop a technology that utilizes low-grade ore. Limonite representative due its complex mineral elemental composition. In this paper, union process was employed separate elements limonite. Firstly, rough concentrate...

The mid-low grade of phosphate ore, rich by the silicate and carbonate gangue minerals needs a special treatment using flotation process. Where collectors play pivotal role. This study was conducted to enrich an untreated ore (without washing, desliming, hydrocycling, etc.), with eco-friendly economic collector based on soybean oil. Different analytical techniques such as UV-Visible, ATR-FTIR s...

The study investigated whether occupational accident risks were equally distributed across age categories over time in the context of production reorganization and work rationalization in a Swedish iron ore mine between 1980 and 1993. Three phases of reorganization, defined by productivity levels, and four age categories were related to age-related accident risk ratios using the Poisson-regress...

Extended ICP-OES and AAS analysis of floated polysulphide concentrate from the Asgat polymetallic ore revealed that contains 0.91% silver, 18.2% copper, 19.4% antimony, 2.03% arsenic 1.6% bismuth together with other elements. The prevailing minerals in are tetrahedrite, bismuthinite, chalcopyrite, arsenopyrite pyrite non-ore i.e. siderite, muscovite quartz. content above was estimated by X-ray ...

Iron ore pellets are sintered, centimetre-sized spheres of ore with high iron content. Together with carbonized coal, iron ore pellets are used in the production of steel. In the transportation from the pelletizing plants to the customers, the iron ore pellets are exposed to different loading situations, resulting in degradation of strength and in some cases fragmentation. For future reliable n...

A significant contemporary challenge for gold mining companies is to define economic process options for treating more complex ore bodies as the less refractory ores become depleted. Demonstration of economic treatment options allows gold companies to maintain and increase their ore reserves. The selection of options to treat a specific ore is significantly impacted by factors such as mineralog...
