Bauxite mining 
"Jharkhand holds a very large potential of Bauxite amounting to a reserve of 117.54 MT (Source-IBM as on 1/4/2005)" - these deposits are found mainly in Lohardaga, Latehar and Gumla districts and the adjoining plateau region. Deep forest cover makes these areas inaccessible. Suitable communication channels are not there. In 2016-17, Jharkhand produced 2,289,825,000 tonnes of Bauxite. Bauxite and laterite (aluminium ore) is found in "villages of Amtipani, Langdatanr, Chirodih, Jalim, Narma, Bahagara and Gurdari of Bishunpur block, Langatanr, Lupungpat and Chota-agiatu in Chainpur block and Hanrup, Serengdag and Jalim in Ghaghra block. The total number of bauxite mines is twenty one". In Gumla district the mines are operated manually/ semi-mechanised methods. After blasting, manual sorting and sizing of bauxite from the run of mine ore is practiced in the mine. Transport 
Bauxite is ferried in trucks from the mines in Gumla and Lohardaga districts to the plants of Hindalco Industries in Muri and Renukoot. Hundreds of trucks carrying bauxite ply on the Netarhat-Bishunpur-Ghaghra-Lohardaga route. However, in 2009, when Maoists torched some vehicles in Ghaghra block, Hindalco mines at Serengdag and Gurdari in Gumla district and Bagru and Pakhari in Lohardaga district were affected.
