Qualitative and Quantatitve Investigation of Industrial Solid Waste in the Iron Ore Extraction and Processing Sectors of Golgohar Mining and Industrial Company

Introduction: In order to achieve sustainable development in mining, waste management is an essential requirement. The current study aimed to examine industrial solid waste produced in Golgohar Mining and Industrial Company, which is a well-known iron ore extraction and processing complex. Materials and Methods: This cross-sectional study was conducted in two phases from March, 2016 through March, 2017. In the first phase, the data related to the production process and quantity/quality of produced wastes were collected through conducting field observations, interviewing production, environmental experts in Golgohar Mining and Industrial Company, and examining the gleaned evidence. In the second phase, the XRF was used to examine the composition of processing tailings following the ISO 9516-1: 2003. Results: In total, 16, 19, and 17 types of industrial wastes were respectively identified in the extraction sector, the magnetite processing plant, and the polycom processing plant of Golgohar Mining and Industrial Company and 12, 14, and 12 types of which (in the same order) were recyclable. The ingredients of iron ore processing tailings encompassed quartz, manganese oxide, iron oxides, aluminum oxide, calcium carbonate, sulfur, potassium oxide, sodium oxide, titanium oxide, phosphorus, chromium oxide, and barium oxide. Thelargest proportion (32.9%) was recorded for quartz in dry tailings. Conclusion: It is essential to pay more attention to recycling in such industries. Improving production processes for retrieve more iron and the use of mineral wastes as raw materials for other industries can reduce the problems associated with such wastes eg low storage space and environmental problems
