The paper studies the peculiarities of building predictive models electricity consumption according to traditional and considered schemes built on concept Smart Grid, as well rapidity changes in mode consumption, chaotic – avalanche-like forms a corresponding series problematic issues. Need be solved today: first all systematization volumes at iron ore mine. This problem is relevant not only ...
Abstract: The huge consumption of iron ores in China has attracted much attention to utilizing low grade complex iron resources, such as high-aluminum hematite-limonite ore, which is a refractory resource and difficult to upgrade by traditional physical concentration processes due to the superfine size and close dissemination of iron minerals with gangue minerals. An innovative technology for a...
Biomining, the biotechnology that uses microorganisms to extract metals from ores and concentrates, is currently used exclusively for processing reduced ores and mine wastes. Metals of economic value also occur extensively in oxidized ores, such as nickel laterites. While these are not amenable to oxidative dissolution, the ferric iron minerals they contain can, in theory, be disrupted by iron ...
Jarosite, KFe(3)(SO(4))(2)(OH)(6), is a secondary iron sulphate often found in acid mine drainage (AMD) environments, particularly in mining wastes from polymetallic sulphide ore deposits. Despite the negative environmental connotation usually ascribed to secondary sulphate minerals due to the release of hazardous elements to aquifers and soils, jarosite acts as an efficient remover and immobil...
Abstract For banded iron formation-hosted deposits accurate boundary modelling is critical to ore-grade estimation. Key estimation fidelity the separation of different domains within ore body, requiring boundaries between domains. This yields both theoretical and application challenges. We present a series solutions for challenges that arise when large-scale employing composition Gaussian Proce...
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 asinawa iron ore is located about 3km to the southeast of penjween town, sulaimaniya governorate, kurdistan region, northeastern iraq near the iraq-iran border. the exposed iron ore deposit is about 60 and 400m wide and long respectively. the present study is the re-study of the geology and geochemistry of the asnawan iron ore deposit and concluded that the country rocks are consist of hor...
SmartTag is a radio frequency identifi cation (RFID) based technology designed to allow tracking of ore from its source through blasting, run-of-mine (ROM) pads, crushers, intermediate stockpiles and fi nally into the concentrator. This paper presents current developments and the future direction of the SmartTagTM ore tracking system, as well as presenting some case studies. Successful applicat...
This paper is based on the open pit to underground mining practice of Daye Iron Mine. The influence mechanism between high-steep slope and non-pillar sublevel caving method is studied by using physical model test. Firstly, engineering geological properties of the choosing typical research section is analysed and generalized. Secondly, the system of open pit to underground mining is developing a...
binders are of prime importance in the agglomeration of iron ore concentrates. in this research, strength and density of briquette produced from the magnetite concentrate of gol-e-gohar were investigated using different binders at various applied pressures. the results showed that peridor was the most effective binder relative to bentonite and lime. for all types of binders, the increase in bin...
