The eastern Democratic Republic of the Congo's (DRC's)
mining industry involves a web of business, military, and industrial interests,
and the average consumer. One of the country's most valuable cassiterite
(tin ore) mines is in Bisie‑tin that allows for more eco-friendly cell
phones and other hand-held technology. Mining
Processing Congo (MPC), located near Christian Peacemaker Teams (CPT) in Goma,
has a significant interest in mining Bisie.
