1988年我院在北京国际发明展览会上获金牌、银奖、铜奖;在广州首届国际专利及新技术设备展览会上获金奖、铜奖。▲刘纯鹏教授发明的“镍铜硫化矿热等离子体一步直接获取高冰镍新工艺”在1988年北京国际发明展览会上获金牌奖。本工艺用热等离子体从镍铜硫化精矿(含Ni 5～10％)中直接获取高冰镍,一次 In 1988, our college won the gold medal, silver medal and bronze medal at the Beijing International Invention Exhibition; and won the gold medal and bronze medal at the first international patent and new technology and equipment exhibition in Guangzhou. ▲ Professor Liu Chunpeng invented the “nickel-copper sulfide ore thermal plasma one step direct access to high ice nickel new technology” in 1988 Beijing International Invention Exhibition won the gold medal. The process uses hot plasma directly from nickel-copper sulfide concentrate (containing Ni 5 ~ 10%) to obtain high-nickel ice, once
