Integrated Optimization can find optimized solutions for a project to define open pit and mine scheduling with greater reliability. This work aims demonstrate how the insertion of geometallurgical variables significantly change financial return project. Two are considered in planning simulations. Specific energy corresponds consumed comminution ore, process recovery measures percentage metal in...

This paper is focused on the tactical design of steel supply chain (SSC). A general mathematical model is proposed to integrate production and transportation planning in multi-commodity SSC. The main purpose is to prepare a countrywide production and distribution plan in an SSC with three layers consisting of iron ore mines as suppliers, steel companies as producers, and subsidiary steel compan...

Mitochondrial dysfunction is a hallmark of beta-amyloid (Abeta)-induced neuronal toxicity in Alzheimer's disease (AD). Here, we demonstrate that Abeta-binding alcohol dehydrogenase (ABAD) is a direct molecular link from Abeta to mitochondrial toxicity. Abeta interacts with ABAD in the mitochondria of AD patients and transgenic mice. The crystal structure of Abeta-bound ABAD shows substantial de...

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...

The Pau Branco mine supplies two blast furnaces with iron ore lumps, and currently, charcoal consumption for pig iron production accounts for 47% of the blast furnaces’ operational cost. A geometallurgical model is presented to support an economic study considering reserve volumes, product quality, and operational costs based on the metallurgical performance of different iron ore typologies. Sa...

Andarian area is located north of Tabriz city, north west Iran, and tectonically is a part of Ahar-Arasbaran magmatic belt. Geology of the area includes Miocene shallow pluton, Cretaceous flysch-type sediments, metamorphic rocks )hornfels and skarn( and volcanic rocks. Mineralization occurred in two stages: primary and secondary. The primary ore minerals include Au, pyrite and stibnite. Malachi...
