Unfitted wagons were 50 shades of grey, if they were painted at all, and fitted ones 50 shades of bauxite, in the early days. The paint mix was probably a standard specification but the austerity economy was still very much in force in the late 40s and early 50s, and the situation on the ground was probably that the paint shops used what they could get hold of to …
The largest bauxite producing companies are Rio Tinto, Alcoa, and Norsk Hydro, which collectively produced majority of bauxite in 2020. Rio Tinto is the largest producer in 2020, mainly due to the ramp-up from the CBG mine expansion in Guinea, stable performance from the Pacific mine and additional volume from the start-up of the Amrun mine at ...
