    Analysis of Turkey's Base Metal Ore Exports by Herfindahl Hirschman Concentration Index
    (2022-09-01) UZUN KART, ELİF; BAŞYİĞİT, MİKAİL; Uzun Kart E., Başyiğit M.
    Turkey produces underground resources through mining activities and brings them into the economy. Some of the produced minerals are exported. One of the most important of these minerals is base metal ores. Base metal ores are mainly exported to China, and its demand for raw materials is constantly increasing. These ores are also sent for re-import after processing to Belgium, which hosts the important smelters of Europe. However, the weight of these countries in the export markets has greatly increased. Therefore they are negatively affecting the market diversity of exports and increasing the risk of market concentration. The Herfindahl Hirschman concentration index was used to investigate and determine the extent of these risks and their impact on metallurgical raw material exports. The results showed that Turkey\"s base metal exports are moderately and highly concentrated and vulnerable to the risk of monopsony. In addition, it has been determined that increasing concentration levels increase the volume of raw material trade.

    Economic potential and environmental impact of metal recovery from copper slag flotation tailings
    (2023-01-01) BAŞYİĞİT, MİKAİL; UZUN KART, ELİF; Gümüşsoy A., BAŞYİĞİT M., UZUN KART E.
    © 2022 Elsevier LtdCopper slag has long been the subject of metal recovery. However, it has become apparent that copper slag flotation tailings can meet resource requirements under certain circumstances. Besides copper, zinc and cobalt can also be obtained from slag tailings. This study investigated the potential of copper slag tailings alongside global metal supply and demand dynamics. It has been emphasized that, such as copper slag, slag tailings can be a new potential resource for global base metals, considering global and domestic copper production, consumption, and base metal prices. In addition, its economic and environmental sustainability was evaluated from a waste management perspective.
