Pilot Plant Leaching Campaign. The chemical composition of the BR used can be seen in Table 1. In total 9.8 t of BR were processed in the pilot over the course of 43 tests, producing 13.4 t of PLS. The pH control of the process proved effective as overall the pH values varied around 2.3 with ± 0.1 in each trial.
The processing of nickel by pressure acid leaching nickel laterite ores at 250 °C results in liquors supersaturated with respect to aluminum, iron, and silica. These can precipitate from the liquor and onto the autoclave interior (scaling). This reduces the availability of the autoclave. This article presents a methodology for characterizing scale using X-ray …
1. Introduction. In recent years, heap leaching technology has become increasingly important in the mining industry as it offers the possibility of treating copper oxide ores (Helle et al., 2005, Quast, 2000).In addition, it has the advantages of low investment, improved working conditions, and lower energy consumption (Dreier, …

Table 2 shows the process parameters of some representative pilot-scale leaching runs that were performed with leaching acid HNO3 and various modes of agitation. The quantitative chemical analysis of Fe and REE contained in the filtered bulk leachate solutions produced in runs 4-6, 10-12, and 14 is quoted in Table 3.
Neomet Process(12) The Neomet Process is being developed by Neomet Technologies, Canada, as a potentially low capex process able to process both limonite and saprolite ores. It is an atmospheric hydrochloric acid leaching process coupled with a patented "atmospheric autoclave" system to regenerate the acid.
In 2008, the nitric acid pressure leaching (NAPL) technology was patented and developed to treat laterite ores in China. In the following year, a pilot plant with an annual processing capacity of 330,000 tons of dry ores was assembled and tested. The pilot-scale tests were documented to illustrate the innovative technology.

The Lithium Hydroxide Process concept is based on a two-stage alkaline leach process. Lithium is first extracted from the silicate mineral in a pressure leaching stage using soda ash. The reaction involves the formation of soluble lithium carbonate and mineral component analcime (NaAlSi2O6·H2O) as the main components.
