This paper briefly discusses the pros and cons of the different processes that are available for the treatment of . gold plant tailings to regenerate and recovery cyanide for recycling, and presents a technoeconomic argument for the incorporation of this technology into many gold plant flowsheets today. INTRODUCTION

Mining is an important industry, accounting for 6.9% of global GDP. However, global development promotes accelerated demand, resulting in the accumulation of hazardous waste in land, sea, and air environments. It reached 7 billion tonnes of mine tailings generated yearly worldwide, and 19 billion solid tailings will be accumulated by …

A simple and sustainable way to recover gold from cyanide solution using magnetic activated carbon synthesized via a solvothermal method has been developed and showed 99.1% recovery efficiency of gold from 10 mg/L solution within 5 h, which is much faster compared to the commercial granular activated carbon.

This review paper explores available literature on the main technique s. of mining tailing recycling and reuse and discusses leading technologies, including the benefits and. limitations, as well ...

"The technical and economic feasibility or re-processing hundreds of millions of tons of tailings in a number of historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term …

Gold grades that are being mined today are on average ten times lower than they were 50 years ago and many new gold discoveries are refractory in nature or deep below the surface of the earth.

the population in its surroundings [1,13–15]. In this scenario, recycling mine tailings can help reduce the number of tailings for disposal. Circular economy, recyclability, recycling, and reuse have been identified as emerging solutions that can drive the multidimensional aspects of sustainability in the mining and metal extraction …

The presence of cyanide in tailings water provides a compelling case in some instances for recovery or recycle of the reagent used to leach gold in the first place (Fleming, 2005). The economic benefit of supplementing make-up cyanide reagent with recovered cyanide from process streams is worthy of consideration, but offset by the capital and ...

There are some reuse and recycling options for tailings such as cemented paste backfill, road construction, brick/ceramic manufacturing, supplementary …

ABSTRACT. The technical and economic feasibility or re-processing hundreds of millions of tons of tailings in a number of historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term ...

The recovery of gold reached 74.45% under a CaO/SiO2 ratio of 1.25 at 1600°С, which indicates a good decrease in the concentrate slag viscosity, Finally, it appears that recovery of gold from flotation concentrate from gold mine tailings can be achieved through dissolve smelting at high temperature.

The recycling system would be based on the economic principle that the costs of excavating, transporting, milling and decontamination of the tailings are spread over a number of different processes, all of which provide an additional income or cost saving to the overall mining operation, and eliminating the need for costly tailings pond ...

Recycling and Reuse of Mine Tailings. This entry is adapted from the peer-reviewed paper 10.3390/geosciences12090319. Mining is an important industry, accounting for 6.9% of global GDP. However, global development promotes accelerated demand, resulting in the accumulation of hazardous waste in land, sea, and air environments.

The phase composition of gold tailings can affect the recycling of valuable and precious metals because of their complex composition. Scholars at home and abroad have conducted a series of studies on gold tail mineral phases. Sheng et al. (2023) studied a Au mine in Laos. The experimental results showed that gold was stored in sulfides ...
