Application practice of BOF Slag tailings in steelmaking process
The present paper introduces the steel production and BOF slag processing techniques in Steelmaking Sector of Bayuquan Iron and Steel Subsidiary, Ansteel. The technology of slag tailings utilization has been developed under the consideration of the properties of slag tailing and the characteristics of slag forming in BOF steelmaking operation practice. The processing of the BOF slag includes ho...
متن کاملRecovery of calcium carbonate from steelmaking slag and utilization for acid mine drainage pre-treatment.
The conversion of steelmaking slag (a waste product of the steelmaking process) to calcium carbonate (CaCO(3)) was tested using hydrochloric acid, ammonium hydroxide and carbon dioxide via a pH-swing process. Batch reactors were used to assess the technical feasibility of calcium carbonate recovery and its use for pre-treatment of acid mine drainage (AMD) from coal mines. The effects of key pro...
متن کاملProcessing and Reusing Technologies for Steelmaking Slag
About 40 million tons of steel slag a year, which is the by-product of iron and steel manufacture, is generated in Japan and the almost all the slag is reused for the materials, e.g. cement raw material, road base course material and civil engineering material, by effectively utilizing its characteristics such as chemical components and mechanical properties. Most of its purposes of uses are to...
متن کاملPreliminary Investigation of Arsenic and Copper in Plants and Tailings at Telfer Gold Mine
The successful establishment of revegetation using native plants is crucial to help phytostabilization of mine tailings. To assess arsenic (As) and copper (Cu) pollution levels and the feasibility of using native plants in rehabilitation of mine areas, a preliminary investigation was conducted to measure As and Cu in mine wastes and native plants at Telfer Gold Mine. The top layer of soil/mine ...
متن کاملArsenic species in weathering mine tailings and biogenic solids at the Lava Cap Mine Superfund Site, Nevada City, CA
BACKGROUND A realistic estimation of the health risk of human exposure to solid-phase arsenic (As) derived from historic mining operations is a major challenge to redevelopment of California's famed "Mother Lode" region. Arsenic, a known carcinogen, occurs in multiple solid forms that vary in bioaccessibility. X-ray absorption fine-structure spectroscopy (XAFS) was used to identify and quantify...
