Abstract
A method for recycling a material may include carrying out a first pass operation. The first pass operation may include preparing an E-waste material and a solid oxide material. The E-waste material may include Fe and Si. The first pass operation may include blending the E-waste material with fluxing agents. The first pass operation may include feeding a furnace with the blended E-waste material and the solid oxide material. The method may include smelting the blended E-waste material and the solid oxide material from the first pass operation to obtain a slag. The slag may include iron oxide and a molten metal. The molten metal may include copper.
Claims29
A method for recycling a material, comprising:
- carrying out a first pass operation, the first pass operation comprising:
- blending an E-waste material with fluxing agents, wherein the E-waste material includes Fe and Si;
- feeding a furnace with the blended E-waste material and a solid oxide material comprising CuO and NiCO3;
- and
- smelting the blended E-waste material and the solid oxide material wherein the solid oxide material causes oxidation of the Fe to form a slag including iron oxide, to obtain the slag and a molten metal including copper.
A method for recycling a material, comprising:
- carrying out a first pass operation, the first pass operation comprising:
- blending an E-waste material with fluxing agents, wherein the E-waste material includes Fe and Si;
- feeding a furnace with the blended E-waste material and a solid oxide material comprising CuO and NiCO3;
- and
- smelting the blended E-waste material and the solid oxide material wherein the solid oxide material causes oxidation of at least one of the Si or the Fe to form a slag, to obtain the slag and a molten metal including copper.
A method for recycling a material, comprising:
- carrying out a first pass operation, the first pass operation comprising:
- blending an E-waste material with fluxing agents, wherein the E-waste material includes at least one of Fe and Si;
- feeding a furnace with the blended E-waste material and a solid oxide material comprising CuO and NiCO3;
- and
- smelting the blended E-waste material and the solid oxide material wherein the solid oxide material causes oxidation of the at least one of the Si or the Fe to form a slag, to obtain the slag and a molten metal including copper.
