2020-10-6 Tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area. Mine sites typically manage tailings by constructing ponds secured by dams. However, some mining companies are figuring out ways to turn tailings to profits with novel reprocessing technologies to extract valuable metals

2021-2-13 $165 Million Gross Year One Revenue projections are estimated from processing 35,000 tons of tailings. This should generate over 78,000 ounces of Gold and 975,000 ounces of Silver. As onsite tailings are processed over 70,000 Tons of Tailings can be supplied from targeted nearby sites. This includes our Johnny Bull and Silver Knight property.

2019-9-13 Thirty or 40 years ago though, processing technologies were generally much less efficient and average recoveries were lower. Metal prices were also much lower. Metals that weren’t recovered were sent to storage along with tailings. This means that the grade of metals residing in legacy tailings is, in some cases, very high

2021-4-15 1. Introduction. Mine tailings are waste obtained after the processing of some minerals to acquire one or more elements of interest. They are composed of a mixture of heavy metals, water, sand, and fine-grained solid material, and generally are deposited in ponds without further treatment (Babel et al., 2016; Santibañez et al., 2012; L. Wang et al., 2017).

2021-1-4 The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989).
