Core Viewpoint - A significant breakthrough in mineral exploration has been achieved with the discovery of a large magnesium dolomite deposit in the Kongtong District of Pingliang City, Gansu Province, with a total resource volume of 700 million tons [1]. Group 1: Discovery Details - The deposit is located in the Zhuangmatai area of the Kongtong District and is found within the Middle Proterozoic Jixian System Wangquankou Formation shallow marine carbonate rock strata, characterized as high-quality magnesium dolomite [1]. - The deposit features advantages such as a large scale, shallow burial, gentle dip, and stable thickness, making it suitable for open-pit mining [1]. Group 2: Resource Estimates - The estimated cumulative identified magnesium dolomite ore within the open-pit mining boundary exceeds 700 million tons, with an additional 300 million tons of dolomite available for comprehensive utilization as construction material [1]. - This dolomite deposit serves as an important raw material for magnesium metal smelting and has significant potential for resource utilization in industries such as refractory materials, metallurgical flux, glass, and ceramics [1].
