Latest Patents
One of Shibayama's latest patents is a chromium-containing water treatment method. This invention provides a cost-effective solution for treating water that contains chromium. The method involves a reduction step where chromium-containing water is mixed with a liquid containing 5-50 ppm of hydrogen sulfide. The mixture is then adjusted to a pH of 3.5 or lower and an ORP of 200-400 mV by adding an acid, effectively reducing the chromium present in the water. Following this, a precipitation separation step is conducted, where a neutralizing agent is added to adjust the solution to a pH of 8-9, allowing for the precipitation and separation of reduced chromium as a hydroxide.
Another notable patent is a method for producing nickel sulfide and a hydrometallurgical method for nickel oxide ore. This invention aims to produce nickel sulfide from an acidic sulfuric acid solution containing nickel while suppressing the particle diameters of the nickel sulfide produced. The method involves blowing hydrogen sulfide gas into the acidic solution, with the addition of seed crystals of nickel sulfide to enhance the process.
