解放前,我国仅有屈指可数的几个铁矿石磁选厂和磁化焙烧磁选厂,浮选厂是空白.建国以来,我国铁矿石的选矿工业伴随钢铁工业的发展,现已先后建成投产大、中、小型铁矿石选厂68座.我国第一座铁矿石浮选厂-鞍钢烧结总厂浮选车间早在1957年就已建成投产,其后又相继建成东鞍山、大孤山、包钢、铁坑、齐大山和姑山等六个浮选或包括以浮选为主的联合流程的选厂(车间).其中,鞍钢烧结总厂浮选车间、东鞍山、齐大山、大孤山选厂浮选车间处理的是沉积变质型矿床(亦称鞍山式类型矿床)
Before the liberation, there were only a few iron ore magnetic separation plants and magnetization roasting magnetic separation plants in our country, and the flotation plant was blank. Since the founding of the People's Republic of China, the ore dressing industry in our country has accompanied the development of the iron and steel industry Completed and put into operation large, medium and small iron ore beneficiation plant 68. China's first iron ore flotation plant - Anshan Iron and Steel Sinter Plant Flotation Workshop as early as 1957 has been completed and put into production, and later have been built in East Anshan, Dagushan, Baotou Steel, Tiekeng, Qi Dashan and Gushan six flotation or flotation consisting of the joint process, including the election process (workshop) which, Angang Sinosteel Flotation Plant, East Anshan, Qi Mountain, Dagushan Flotation Plant election processing plant is deposited metamorphic deposits (also known as Anshan type deposit)
