Bibliometric Analysis of Gold Tailings Treatment and Comprehensive Utiliza-tion Research
With the rapid development of China's economy,the traditional model of crude economic growth has exacerbated resource shortages,and intensified environmental pressure.Consequently,the vigorous development of a green,circular economy and the improvement of resource utilization rates are imperative.Gold tailings,a form of solid waste,are produced as a byproduct of the extraction and processing of gold mineral resources.Gold production predominantly utilizes the cyanide extraction method,necessitating the addition of cyanide during the process.Consequently,residual cyanide remains in the tailings,contributing to environmental pollution and posing risks to human health.Furthermore,as the scale of gold production expands,the accumulation of gold tailings increases annually,leading to significant land occupation.In China,the comprehensive utilization rate of metal tailings averages less than 10 percent,which is markedly lower compared to other bulk solid wastes.Gold tailings are rich in both heavy metal elements and valuable minerals,improper management not only results in the wastage of natural resources,but also poses significant safety risks.Bibliometrics,the application of mathematical and statistical techniques to quantitatively analyze information within the literature of a specific field,can elucidate the characteristics of research activities and identify emerging trends in that domain.Employing bibliometric methods and VOS viewer software,this study aimed to elucidate the research dynamics pertaining to the treatment and comprehensive utilization of gold tailings,both domestically and internationally.The findings indicate a growing trend in research on gold tailings treatment and comprehensive utilization,with close inter-country research linkages and a steadily improving comprehensive utilization rate of gold tailings in China.The research in this field predominantly focuses on three directions,namely flotation of gold tailings,comprehensive utilization of gold tailings,and ecological restoration of gold tailings.Innovations in separation and purification technologies for various components in gold tailings,have the potential to enhance the comprehensive utilization of these tailings,thereby increasing their added value.Such advancements can facilitate the quantitative reduction,resource utilization,and high-value application of gold tailings.Currently,the overall comprehensive utilization of gold tailings,both domestically and interna-tionally,is increasing.However,challenges remain in the resource utilization of gold tailings,necessitating further in-depth research.It looks forward to the future development direction of harmless treatment and high value utilization of gold tailings.The comprehensive utilization of gold tailings can turn waste into treasure,turn harm into benefit,and alleviate the prominent contradiction between China's economic development and ecological environment destruction and resource shortage.
