Examining Soil Erodibility, Soil pH, and Heavy Metal Accumulation in a Nickel Ore Mine: A Case Study in Tubay, Agusan del Norte, Philippines

Mining activity always presents threats to soil and water pollution. As an extractive industry, it disturbs the ground biodiversity associated with plants. Its operations have led severe geological environmental problems, including depletion of land resources, dangers, ecological landscape devastation that may accelerated desertification mining areas. This case study analyzed soil’s physical chemical properties in a nickel laterite mine, erodibility K factor, pH, heavy metal accumulation, as basis for establishing mine management protocol during post-mining Tubay, Agusan del Norte, Philippines. Results determined slightly alkaline pH level. An estimate ranging from 0.016 0.066 was using USLE-K highest at Mine 7, where % silt is high sand lowest. X-ray fluorescence (XRF) spectroscopy used analyze samples. The findings show Ni, Fe, Co, Mn were above WHO-permitted limits. surface had mean values 9,239 ppm nickel, 302,618 iron, 639 cobalt, 5,203 manganese. Heavy metals be consumed by crops pollute water.
