Extraction
Extraction is a fundamental process in chemical engineering where valuable materials are separated from mixtures using various methods. Think of it like brewing tea, where hot water pulls out the flavors from tea leaves. In industry, extraction is used to obtain essential oils from plants, separate oil from seeds, or remove valuable minerals from raw materials. Companies use this process in many industries, from food and beverages to pharmaceuticals and oil refining. When you see this term in a resume, it usually indicates the candidate has experience with separation processes and purification methods.
