Latest Patents

Vanessa holds a patent for a process titled "Process for the instantaneous control of precipitation of nickel and cobalt present in the leach liquor, by adjusting the pH of the solution." This invention addresses the challenges associated with the pressurized acidic leaching of laterite ores. The process involves several steps, including the precipitation of aluminium, ferric and ferrous iron, and chromium by adjusting the pH-value through the addition of suitable reagents such as lime or limestone. Following this, nickel and cobalt are precipitated by further increasing the pH-value, allowing for the separation of the precipitate from the low-content nickel and cobalt solution. The precipitate can then be refined for further use.
