  • Method and system for metal recovery from arsenical bearing sulfides ores
    Patent number: 11408051
    Abstract: There is provided a method for the removal of arsenic from an arsenical bearing sulfides ore, comprising a thermal treatment of arsenical sulfide in the presence of sulfur dioxide, yielding a calcine and a sublimate, the sublimate containing arsenious oxide. The method allows recovering metallic value from an arsenic-bearing metallic sulfides ore, by recovery of the calcine comprising the metallic value of the ore.
    Type: Grant
    Filed: January 22, 2018
    Date of Patent: August 9, 2022
    Inventors: Jean-Marc Lalancette, David Lemieux, Romain Barbaroux, Gabriel Garcia-Curiel, Khalil Nasrallah

  • Method for vitrification of arsenic and antimony
    Patent number: 9981295
    Abstract: A method for vitrification of arsenic and antimony, comprising substituting oxygen to sulfur on thiosalts, incorporating resulting sodium arsenate and sodium antimonate into a sodium silicate glass-forming mixture and vitrifying the sodium silicate glass-forming mixture into a resulting glass sequestering the arsenic and antimony.
