摘要： Some variations provide a composition for reducing a metal ore, the composition comprising a carbon-metal ore particulate, wherein the carbon-metal ore particulate comprises at least about 0.1 wt% to at most about 50 wt% fixed carbon on a moisture-free and ash-free basis, and wherein the carbon is at least 50% renewable carbon as determined from a measurement of the 14 C/ 12 C isotopic ratio. Some variations provide a process for reducing a metal ore, comprising: providing a biomass feedstock; pyrolyzing the feedstock to generate a biogenic reagent comprising carbon and a pyrolysis off-gas comprising hydrogen or carbon monoxide; obtaining a metal ore comprising a metal oxide; combining the carbon with the metal ore, to generate a carbon-metal ore particulate; optionally pelletizing the carbon-metal ore particulate; and utilizing the pyrolysis off-gas to chemically reduce the metal oxide to elemental metal, such as iron. The disclosed technologies are environmentally superior to conventional processes based on coal.

By taking an electronic circuit board copper-containing waste etching solution (HW22) as a raw material, and adding soluble salt corresponding to a dispersed phase (one, two or more of Al 2 O 3 , Y 2 O 3 , MgO, ZrO 2 and ThO 2 ), Cu(OH) 2 /X(OH) n composite powder is prepared by a chemical neutralization and precipitation process, and nano-oxide dispersion-strengthened copper is obtained through processes such as calcination, selective reduction and densification. The prepared nano-oxide dispersion-strengthened copper material has high strength, high conductivity and excellent high temperature softening resistance: its room temperature tensile strength is greater than 600MPa, its electrical conductivity is greater than 80% IACS (International Annealed Copper Standard), and the softening temperature is higher than 700 DEG C. The method provided by the present invention is simple in process, short in flow, low in energy consumption, and low in cost due to abundant and easily available raw materials, thereby being suitable for large-scale industrial production.
