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...

Mining processes in the iron ore mine of Boukhadra, Tebessa (NE Algeria) generated thousands tons mining wastes every year, which represents a real threat to environment, leading hazardous effects for resident population region. The aim this study is selective sorting Boukhadra valorization. This will facilitate recycling mineral substances (limestone, iron, marls) on one hand and it makes poss...
