Silangan, located in Surigao del Norte province on the mineralrich island of Mindanao, was scheduled to begin production in 2018.
Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between % and 5% copper, with gold contents ranging ...
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

The goal of assaying and testing any potential gold and silver bearing materials is to determine their metals content. While it is sometimes possible to look at a sample and guess its possibilities, more often than not, in order to have an accurate idea of how valuable in ore is it must be analyzed.
When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
