Iron ore is one of the most sought-after mining materials because of its high economic value, the potential for primary iron ore (ironstone) in West Sumatra is quite large, does this potential have a large quantity of raw material and the quality of its metal content is of good quality and how is the impact of West Sumatra smelter production? for future consumption, production, and import of national iron ore. This research method uses a literature review of various iron ore mining companies, district and provincial mining and energy offices, government regulations, ministerial data, and others related to industrial smelter development planning. Analysis of the quantity and quality of ironstone resources (primary iron) in terms of the amount and content of metal content of ironstone mining minerals (primer iron), analysis of supporting factors for the smelter industry, and analysis of the impact of projected output from the smelter industry on the needs of consumption, import, and production of iron National, using Least Square linear regression. The research results show that the quantity of primary iron ore (ironstone) reserves in 32 iron ore mining companies in West Sumatra, has several raw material stocks: Tereka MT indicated MT, Measured MT, Estimated MT, and Proven MT with the amount of raw material stock. primary iron ore (ironstone) reserves are enormous. Meanwhile, the quality of primary iron ore (ironstone) reserves has an average content of iron (Fe) and good quality Fe203, above fifty percent. Energy resources and road and port infrastructure support smelter construction. The projected impact of West Sumatra smelter production in 2022-2030 has a significant impact on the consumption and import needs of iron in Indonesia.
