About Us
Water is also added, which turns the ore into a slurry. We send this slurry to leaching tanks, where we add a weak cyanide solution to the slurry, which leaches gold and silver into the solution. This process removes up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution.

The unit value to be gained from processing material from stockpile is divided by M to account for the probability of a simulated …
Indonesia's Nickel Industrial Strategy
Indonesia's nickel strategy is part of the country's commodity-led development strategy. The country's general approach—sometimes referred to as "resource nationalism"—is guided by the 2009 Mineral and Coal Mining Law ( Law No. 4/2009 ). It is linked to Indonesia's constitution of 1945, Article 33, which states that land, waters ...
