Genesis type of ore deposits indicated by trace elements of chalcopyrite
地质科技通报, 2023 Trace elements of metallic minerals are important to constrain the formation processes and genetic types of ore deposits. Trace elements have been mainly focused on pyrite, magnetite, and sphalerite but have rarely been applied to chalcopyrite. To reveal

EBSD-Based Characterization of Pyrite in the Kiskamavaara IOCG Deposit
Cobalt (Co) is a metal of increasing global importance, primarily due to its crucial role in battery performance, longevity, and energy density. Demand for Co is projected to grow significantly with the acceleration of fossil-free energy transitions, largely driven by battery storage and electric vehicles. The Kiskamavaara deposit in northern Sweden is

Favorability potential for IOCG type deposits in the Riacho do Pontal Belt: new insights for identifying prospects of IOCG-type deposits in NE Brazil [PDF]
Brazilian Journal of Geology, 2018 ABSTRACT: Archean iron oxide-copper-gold (IOCG) deposits have been systematically described in the world class Carajás IOCG district, Amazonian region of Brazil. More recently, several Neoproterozoic (ca 1.13 to 0.96 Ga) IOCG deposits have been identified in the Riacho do Pontal mobile belt situated in the Borborema Province on the northern border of ...

Resource Geology, Volume 70, Issue 3, Page 296-308, July 2020., 2020 Geochemical results indicate no significant contamination occurred in the surface water due to the mining activity and beneficiation process of hematite and limonite ores in Pipet iron deposit, Myanmar. Bulk mineralogical and chemical analyses of ore samples demonstrated that some limonite ore samples contain significant amounts of Arsenic (up to 2 wt%)
