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...

Human and animal skeletal remains can provide information about the food chain of inhabitant’s nutrition of archaeologicalsites. The food chain which at it minerals and organic materials transferred from soil to the plants, from plants to theanimals, and from herbivores animals to the carnivores, is the benchmark system in ancient diet. Although Chemicalinteractions between soils, animal and hu...

during the course of our studies on archaeometallurgy in southeastern iran, we tried to survey the triangle of the sirdjān, neiriz and shahr- e- bābak. as a result, remains of old iron mining residues of smelting furnaces, and iron smelting slag heaps were observed and recorded. a few samples of iron ore and smelting slag have been analysed classically and instrumentally. according to the acq...

Naphthalene is an ubiquitous pollutant of the environment and the biodegradation of this pollutant has been receiving constant scientific consideration. The aim of this study was to isolate and identify bacteria that could degrade naphthalene from three regions of the Gol Gohar Mine at Sirjan, Iran. In this study, the total naphthalene degrading bacteria were quantified with the most probable n...

Vertical silos are large cylinders used for material storage in agriculture and mineral industries. One of the silo problems is its obstruction due to dome and dense packing. Depend on the material properties and silo dimensions several techniques are used to solve this problem. In the present work, possibility of obstruction solution of a laboratory silo by ball impact is investigated. Test ma...
