as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.
DEVELOPMENTS IN THE PRETREATMENT OF REFRACTORY GOLD MINERALS BY NITRIC ACID 145 Introduction The recovery of precious metals from refractory ores has previously received considerable attention (Gao, et, 2022; Miroslav 2022; Gao, et al., 2022; Hu and David, 2022; Chen, et al., 2022; Li, 2003a, 2003b; Zheng, 2022).

Gold Mining Operation: 10 - 30 years. The gold mining operation stage represents the productive life of a mine, during which ore is extracted and processed into gold. Processing involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold.
The development of heap-leaching and dump-leaching technologies for low-grade ore has extended the world's ore resource base considerably. The processes were developed by the copper industry and the USBM and have been extended to uranium and gold.

In much of the developing world, a lack of access to power, clean water and transport infrastructure is a significant barrier to economic development. Gold mining often takes place in remote areas where there is little existing infrastructure, so companies invest heavily in building power supplies, piped water and roads, which can create important benefits for local communities. Infrastructure, from roads to power
