In its natural form, Kyanite is non-hazardous, but biological, chemical, and engineering methods, which are adopted during processing, may generate various hazardous by-products. On this note, it is the responsibility of miners to eliminate the probable hazards during mining and processing of minerals (216). Works Cited. Government Office.Web

Liquid wastes associated with the mineral mining industry can be separated into three major categories: 1) mine dewatering (mine pumpout from surface and underground mines); 2) process wastewaters (spent waters used in transportation, classification, washing, separation, and pro- cessing of ores); and 3) surface runoff (precipitation that falls ...Web

tailings are used in dump or heap leaching, a process that the mining industry considers a form of beneficiation and one that involves spraying the material with acid or cyanide to leach out metals. This process is most widely practiced in the copper, silver, and gold mining segments, and the associated wastes are termed dump/heap leaching wastes.Web

Kyanite is found directly inside of metamorphic rock, where it forms as a result of contact metamorphism. Because of its location and its composition, this stone has perfect cleavage in two directions. This makes it extremely fragile and breaks easily during the mining process.
