Rahman Hydraulic Tin Ore Mine has been in operation in Klian Intan, Hulu Perak since 1907. The mining company carried out the largest mining activities of hard rock tin ore in Malaysia. The use of hydraulic pumps to extract tin ore into the hearth distinguishes Rahman Hydraulic from other mines.

At present, Rahman Hydraulic's tin ore mine is still operating as an open mine. Interestingly enough, it has now become an educational spot for the current and future generation in addition to it becoming a tourism focal point.
