“…The tailings water, after the filtering process of the mineral ores, contains a much higher concentration of heavy metals. For example, for the Navodari mine site, the tailings water contains cadmium up to 29 ppm, fluorine up to 105-207 ppm, sulphates up to 1100-1720 ppm, and phosphates up to 1270 ppm [10]. The tailings water with a high concentration of heavy metals can significantly damage the habitat environment of plankton and benthic nekton, which can increase the concentration of heavy metals in fishes.…”

Abstract:Deep sea mining tailings disposal is a new environmental challenge related to water pollution, mineral crust waste handling, and ocean biology. The objective of this paper is to propose a new tailings disposal procedure for the deep sea mining industry. Through comparisons of the tailings disposal methods which exist in on-land mining and the coastal mining fields, a new tailings disposal procedure, i.e., the submarine-backfill-dam-reuse (SBDR) tailings disposal procedure, is proposed. It combines deep sea submarine tailings disposal, backfill disposal, tailings dam disposal, and tailings reuse disposal for the deep sea mining industry. Then, the analytic network process (ANP) method is utilized to evaluate the performances of different tailings disposal methods. The evaluation results of the ANP show that the new proposed tailings disposal procedure is the most suitable for the deep sea mining industry.

“…Flotation tailings of the metallic ore flotation processing plants represents a potential threat to the environment, both because it contains flotation reagents and heavy metals minerals that due to the effects of atmospheric precipitation may enter the aquatic environment, and the fact that this material is comminuted and can induce pollution of the air and the surrounding land by wind (Golomoev et al, 2011;Benvenuti et al, 1997;Komnitsas et al, 1998;Panias, 2006). In addition to these environmental hazards there are also risks of dam rupture and spilling polluting materials into the waterways.…”

Flotation tailings dumps represent a potential threat to the environment. To corroborate this, numerous environmental disasters have occurred worldwide in the past. Pollution caused by breaking of tailings dump dams and overflowing of hazardous materials is still present, after several decades, and continue to threaten the environment. This paper presents a method for determining the most appropriate location for the flotation tailings dump using rough set theory. The review of the criteria that influence the choice of flotation tailings dump location is given. Based on these criteria, an analysis and evaluation of the proposed locations for the flotation tailings dump are done using rough set theory and the most suitable location that meets all the requirements is suggested.Keywords: flotation tailings, environmental disasters, location, rough set theory, decision making, criteria Składowiska odpadów poflotacyjnych stanowią potencjalne zagrożenie dla środowiska naturalnego. Dla potwierdzenia, wymieniać można różnorakie katastrofy dla środowiska, które miały miejsce w przeszłości. Skażenie spowodowane przerwaniem tam zabezpieczających składowiska utrzymuje się nadal, nawet po upływie kilku dekad a przelewanie się materiałów niebezpiecznych wciąż stanowi zagrożenie dla środowiska.W pracy przedstawiono metodę wyboru najodpowiedniejszej lokalizacji składowiska odpadów poflotacyjnych w oparciu o teorię zbiorów przybliżonych. Zaprezentowano przegląd kryteriów w oparciu o które dokonuje się wyboru lokalizacji składowiska. W oparciu o powyższe kryteria, przeprowadzono analizę i ocenę proponowanych lokalizacji składowisk odpadów poflotacyjnych przy zastosowaniu teorii zbiorów przybliżonych i na tej podstawie dokonano wyboru odpowiedniej lokalizacji, spełniającej wszystkie powyższe kryteria.Słowa kluczowe: odpady poflotacyjne, katastrofy środowiskowe, teoria zbiorów przybliżonych, procesy decyzyjne, kryteria

“…Dentre as alterações ambientais promovidas pelos rejeitos pode-se citar a supressão de áreas de vegetação, reconfiguração de superfícies topográficas, impacto visual, aceleração de processos erosivos, inviabilidade de uso alternativo do solo, emissão de gases e partículas no ar, aumento da turbidez e assoreamento de corpos d'água, geração de drenagem ácida, contaminação dos recursos hídricos e comprometimento da qualidade de vida da população do seu entorno. [7][8][9] Desta forma, a busca de alternativas de tratamento destes efluentes, bem como, do aproveitamento econômico dos rejeitos é de suma importância para minimizar os seus efeitos sobre o meio ambiente.…”
