Mineral Processing
Mineral processing techniques have been suggested for the recovery of nickel-based alloys from spent batteries. The process involved hammer milling, magnetic separation, knife milling, a second and a final magnetic separation, and size separation. The AB 5 alloy type from Ni–MH batteries can be used as an alloy in stainless steel.
Carbon Cycle
The process of photosynthesis involves the absorption of CO 2 by plants to produce carbohydrates. The equation is as follows: CO 2 + H 2 O + energy → (CH 2 O) n +O 2. Carbon compounds are passed along the food chain from the producers to consumers. The majority of the carbon exists in the body in the form of carbon dioxide through respiration.
