Aparri is a municipality in Cagayan province in the Philippines located at the mouth of the Cagayan River. Black sand mining operations in Punta, Aparri operate 24/7 using backhoes, dump trucks, and processing equipment to extract magnetite from the black sand deposits. However, the mining exacerbates flooding and riverbank erosion, reduces fish populations, and spreads dust into nearby homes from the processing equipment. Local groups are concerned about the environmental impacts of the black sand mining.
