The extraction of metals CPD RSC Education
Carbon can be used to extract metals from some metal oxides. • A metal can either be reduced or oxidised in a reaction. • Reduction occurs when a metal in a compound loses oxygen, to form the Several processes are used for extraction of same metal depending on occurrence and chemical requirements. It takes multiple steps to extract the "important" element from the ore: First, the ore must be separated from 23.2: Principles of Extractive Metallurgy

Metals extraction processes from electronic waste:
The skyrocketing demand and progressive technology have increased our dependency on electrical and electronic devices. However, the life span of these devices has been shortened because of rapid scientific expansions. Hence, massive volumes of electronic waste (e-waste) is generating day by day. Nevertheless, the ongoing The by-products produced from fruit processing industries could be a potential hazard to environmental pollution. However, these by-products contain several biologically active molecules (essential fatty acid, phenolic compounds, flavonoids, coloring pigments, pectin, proteins, dietary fibers, and vitamins), which can be utilized for various Review on the extraction of bioactive compounds and
