The name Caxangá does not have a very clear origin. Some authors claim that it is a corruption of the tupy word caa-çan-áb, which means extended forest or caa-çang-gua, weeds of the dilated valley, or even caa-ciangá, weeds of the stepmother or godmother.
Caxangá mill is located in the municipality of Ribeirão, on the right bank of the Amaragi River, and it was founded by the planters Arthur de Siqueira Cavalcanti and the brothers Ethelmino and Antônio Bastos.
