過去地質工作对于工業用石灰岩的調查研究,是非常缺乏且沒有給以应有的重視,因而今天在全面的進行矿物原料的勘查研究當中,石灰岩舆其他輔助原料矿物一樣,還是我們的主要對象之一。因为我們在黑色冶金工業中,不僅必須有足够的优質的鐵礦,同时业必须有保证足量合用的煉焦煤、錳矿、石灰岩、螢石和各種耐火材料等,否則要想建成大规模的现代化的黑色冶金 In the past, the geological work for industrial limestone research and research was very scarce and did not receive due attention. Therefore, today, in the comprehensive exploration and research of mineral materials, limestone and other auxiliary minerals are still our main target. one. Because in the ferrous metallurgy industry, we must not only have enough high-quality iron ore, but also must have enough coking coal, manganese ore, limestone, fluorite, and various refractory materials to ensure a large-scale modernization.
