The Lut Block is a potential porphyry-style mineralized region in Iran including the well-explored Shadan porphyry gold-copper deposit, which has an extensive zone of gold- and copper-bearing stockwork-like sheeted veins. structural setting this deposit key to understanding genesis mineralization. Our field studies show that mineralization occurs as steeply dipping ore bodies along NW–SE transp...

post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. sungun, nw iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. in this study, simple directional vario...

Brambang is one of the porphyry copper-gold prospects/deposits situated along eastern Sunda arc. This study aimed to understand geological framework, alteration geochemistry and ore fluid characteristics prospect. Fieldworks various laboratory analyses were performed including petrography, microscopy, rock geochemistry, chlorite chemistry inclusion microthermometry. The prospect composed andesi...

The crude oil market is significantly larger than that for any other commodity, both in terms of physical production and financial market activity (Table 1). The value of crude oil production is more than twice that of coal and natural gas, 10 times that of iron ore and almost 20 times that of copper. Crude oil is the most widely used source of fuel, supplying around one-third of the world’s en...

Heap leaching accounts for a fifth of global copper production, sourced primarily from porphyry ores, yet metal recoveries are often not optimal. Gangue, and its interaction with acid, plays an important role in such processes. Thus, a proper understanding of gangue minerals present in the ore, their textural relationships relative to particle size distribution, reactivity with acid under diffe...

Since the start-up of Sossego copper concentrator, located in Carajás Mineral Province southeast Para State, Brazil, low-grade ore (~0.34% Cu) has been stockpiled, as defined long-term mine plan, to be reclaimed at end life. Given this imminent need process around 40 Mt ore, questions have raised related extent oxidation that might occurred stockpiled ore. In context, a study was designed chara...
