Chapter 4: Mining waste

CHAPTER 4: MINING WASTE. This chapter covers the different types of mining waste, how they are formed and how they are disposed of or used. Mining operations can generate enormous amounts of waste (i.e. waste rock and tailings) that must be managed and handled in a way that avoids negative environmental impact.

It is a process usually applied to low grade gold ore. Basically the ore is piled to a given height on an inclined impermeable surface, a so called leach pad. A sprinkler system provides a continuous spray of alkaline cyanide solution that percolates through the ore dissolving the gold. The gold bearing or

Researchers find cyanide-free gold leaching process

The Curtin process requires none of these. Co-research lead and chair for extractive metallurgy for the Future Battery Industries Cooperative Research Centre Jacques Eksteen said the technology used a low concentration of the strong oxidising agent potassium permanganate, which produced better results compared with other oxidants for the alkaline glycine gold leach system.

Gold mining

Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include grinding, concentration, roasting, and pressure oxidation prior to cyanidation.

Gold Extraction & Recovery Processes

Changes in ore properties, such as ore gold distribution and hardness have influence in gold liberation and consequently will be affected the recovery process. For example, orebodies containing clays have problems due to the excessive amount of fine material liberated during the comminution process due to rheological and physiochemical properties are modified.
