The cost of transporting imported bauxite in Guizhou is generally higher than in other parts of China, even compared to Shanxi and Henan, where it is 30-50 yuan more expensive. However, due to factors such as the relative price advantage of several mines, tight supply of domestic ore, and favorable indicators that are conducive to increasing production and reducing costs, alumina enterprises in inland Guizhou are trying their best to reduce transportation costs and, under the premise of relatively stable alumina prices, increase the application of several mines to achieve cost reduction and efficiency improvement.
