What the project involved
This is the case where the integrated model is easiest to see. Xinhai carried the engineering, the equipment supply, the construction and then the operation, providing management and key technical personnel on site.
At 1.2 g/t, the margin between a plant that works and one that does not is thin, and it is decided in the leaching and adsorption circuit. The reported result is an overall recovery held stable at around 93%, which is a function of grind size control, leach residence time and carbon management rather than of any single piece of equipment.
Cross-process coordination is what the operation contract actually buys: mining supplies the plant with feed of a known character, and the plant is tuned for it, instead of each side optimising separately.
