The discovery of substantial tin deposits in the Kinta Valley attracted a diverse influx of immigrants, particularly from China, who sought their fortunes in the lucrative mining trade.

A railway line linking Ipoh and other town in Kinta such as Pusing, Papan, Siputeh and Tronoh was completed in 1909 and used to transport tin ore.

Some areas in Sungai Raia such as RPT Tekah 1, RPT Tekah 2, RTC Gopeng & Gopeng Industrial Park are administered by the Kampar District Council even though they are located in the Kinta district.
