Latest Patents
One of Halim's latest patents is titled "Removal of arsenic from contaminated aqueous solutions." This invention discloses processes for effectively removing arsenic from contaminated waters and process solutions. The method involves precipitation with a soluble iron compound or solvent extraction, followed by treatment with engineered materials such as granular iron oxide. Additionally, arsenic can be directly removed from contaminated ground and surface waters using engineered materials, particularly by contacting these waters with silica and granular iron oxide. The treated solutions can then be safely released into the environment.
Another notable patent is "Recovery of nickel in leaching of laterite ores." This invention provides a process for leaching laterite ore or concentrate to recover valuable metals, specifically nickel. The process utilizes hydrochloric acid as a lixiviant to leach nickel from the ore. Nickel is then extracted using an oxime at a lower pH, which is particularly effective after separating iron and cobalt values.
