As a result, you want ore processing systems to be flexible - allowing different ores to go on different routes. You also want to be able to automatically pull out things at any step of the process. For example, Rare Earths from GT++ require much higher power load, which would cause your existing macerator line to choke without modifications.

Classification of Ore DepositsUnit 2 by shiny gold and copper which are found free in nature and used them originally as ornaments. Likewise, minerals are known since ancient time. The early men were aware of ore deposits and many of them worked on various types of ore deposits. They used cinnabar and soft red hematite as pigments
The technological processing flowsheet for gold-bearing ores varies widely. The choice of a particular technological flowsheet depends on several factors, including the nature of the gold in the ore, especially its size and chemical composition, the nature of the minerals associated with the gold, the presence of other valuable components in the ore, and the …

The pyrite contains 43.36% Fe and 41.26% S. The occurrence of gold in the different phases of the sulfide refractory gold ore is shown in Fig. 2, which indicates that 93.94% Au is encapsulated, especially, sulfide-encapsulated gold up to 80.85%. The X-ray diffraction (XRD) pattern of the sulfide refractory gold ore and pyrite is shown in Fig. 3.
To understand the various innovations in mineral processing, we will need to under - stand the various challenges the mining industry has handled so far.
