Pyrite is an iron sulfide byproduct generated by copper mining at MDKA's Wetar mine in Southwest Maluku. Efforts to add value to pyrite have been part of the company's plans since 2019. The smelting process at the Wetar mine previously only yielded copper, leaving byproducts that could not be further processed.

However, pyrite waste is potentially reusable. Therefore, this study aimed to evaluate possible ways of waste and effluent valorization that are generated during the processing of coal mining pyrite (R1). Raw R1 were subjected to two consecutive leaching processes in distilled water (20 g/L, 70 °C) under mechanical stirring for 40 min.

Depending on the location and scale, mining methods may include open-pit mining or underground mining. Open-pit mining involves removing the overburden and extracting pyrite from the exposed ore body. Underground mining, on the other hand, involves tunneling into the Earth to access pyrite deposits in veins.

Since soils were collected near a sink pool of acid mine drainage (AMD) derived from pyrite mining, the pH of the soil was highly acidic (pH = 3.05). The labile fraction accounts for 17.72% of total Tl, with its content in the acid extractable, reducible, and oxidizable fractions of 0.79, 0.52, and 0.63 mg/kg, respectively.
