Abstract

In the event of occupational accidents in mining, investors can calculate approximately how much loss will be incurred at the time of the accident. However, in halting mining as a result of occupational accidents or legislation, investors, will perhaps not care about how much of a loss to profits will arise due to the resulting downtime of mining operations. The reason for this is that there is no such halting in mining operation as yet and mining activity is continued. Avoiding halting mines due to occupational accidents and legislation would enable the prevention of unexpected costs resulting from these time losses. The aim of this study was to find out how much the loss of profits resulting from the downtime of mining enterprises due to the aforementioned reasons are in total, and how much the ratio of loss of profits to annual operating costs is on average on an annual basis. To determine the loss of profits and to minimize the accidents in enterprises, permanent supervisors, who are assigned in the enterprises where they are working, were given a survey through the SurveyMonkey program. Of the 235 permanent supervisors who filled out the survey on behalf of the mining enterprises, 58 answered all of the multiple-choice questions examined in the study. These questions were analyzed together according to different mineral groups and differences in mining operation methods. As a result of the analysis, it was determined that the annual loss of profits of mining enterprises resulting from the aforementioned periods of downtime, and the ratio of these values to the annual operating costs constitute a rather significant share. The aim of the article was to raise awareness to have mining companies appropriate more funds for occupational health and safety.

Abstract

During the extraction of nuclear raw materials, rare earths and other elements from ores containing uranium and thorium, various types of radioactive waste and some recovery tailings are generated. Mining and ore processing residues, i.e. waste and tailings, present a variety of problems related to waste management. Their bulky structure prevents their disposal underground, and their long radioactive half-life causes various problems with regard to their long-term storage. As a matter of fact, the secondary presence of nuclear raw materials together with other minerals requires compliance with hazardous waste procedures in the storage of waste containing nuclear raw materials after the recovery of these main minerals. It may be possible in the future to recover these nuclear raw materials from stockpiles of stored mine waste. The prospect of imbalances in the global uranium supply and demand increases the importance of secondary sources contributing to the global uranium supply. The increasing importance of secondary sources of nuclear raw materials suggests that more attention should be paid to the recovery of these resources together with primary minerals than in the past. In world literature, there is no review article that describes and discusses the waste management of nuclear raw materials in mining and mineral processing together with the opportunities and obstacles for their recovery. Considering this deficiency in the literature, in this study, the properties of waste and tailings resulting from mining and ore preparation activities of nuclear raw materials are explained, the difficulties encountered are mentioned, and solution suggestions are presented by making use of the literature on the recovery of tailings and waste management.
