Imaging of inner structures: nowadays there is a request for noninvasive techniques in diagnostics, and hence invasive ones are restricted to presurgical examinations and interventional radiology.
Chemical Used in Gold Mining "Refractory Gold ore" Kemcore ... The clean roasting technology provides a process for refractory gold concentrates treatment which should be highly efficient and cost effective with distinct advantages over competing treatment processes combined with full environmental compliance.
Following the hot commissioning process of the POX Hub and supporting equipment, announced 27 November 2018, the Company began processing refractory concentrate through Autoclave 1. The process of sulphide oxidation inside the autoclave vessel is working well, achieving gold recovery of 93%, close to projected design recovery of 98%.

Refractory manufacturing involves four processes: raw material processing, forming, firing, and final processing. Figure illustrates the refractory manufacturing process. Raw material processing consists of crushing and grinding raw materials, followed if necessary by size classification and raw materials calcining and drying.
Autoclaves are used in mining and minerals processing to extract metals from refractory ore bodies. A typical process for autoclaves is highpressure acid leaching (HPAL), which is often used to extract nickel from laterite ore bodies, but it can also be applied in copper and cobalt production.
