Outline
In order to accurately predict the supply-demand situation and guarantee degrees for important mineral resources in Liaoning Province during the 14th Five Year Plan period, based on the development and utilization of mineral resources during the 13th Five Year Plan period, the method of demand trend analysis was adopted to track the industrial chain, and the development and utilization data of upstream and downstream production links or consumption data of downstream product end markets were collected. The demand and guarantee capacity of iron ore, coal, gold ore, magnesite, flux limestone, and boron ore during the 14th Five Year Plan period were predicted. The accuracy of the prediction results was verified by the actual yield and consumption of each mineral in 2021 and 2022. The results show that the demand for iron ore ranges from 183.75 million to 191.1 million tons per year, coal from 179.92 million to 191.35 million tons per year, gold ore from 8.11 million to 8.92 million tons per year, magnesite from 30.48 million to 33.81 million tons per year, flux limestone from 14.96 million to 15.4 million tons per year, and boron ore from 4.16 million to 5.39 million tons per year in the next 5 years. The guarantee degree of magnesite and flux limestone is relatively high, which can achieve supply-demand balance. Gold ore requires a large amount of imports, and the guarantee degree of iron ore, coal, and boron ore is insufficient. It is necessary to further strengthen the exploration of deep and peripheral mineral resources and improve mining capacity construction.
