One common type of oil seal is the lip seal, which features a flexible lip that makes contact with the rotating shaft to create a tight seal. Lip seals are often used in automotive engines, gearboxes, and industrial pumps due to their effectiveness in preventing oil leaks. Another popular option is the mechanical seal, which uses a rotating element to maintain constant contact with the shaft, ensuring a reliable seal even at high speeds and pressures.

Moreover, the use of leaching agents is pivotal in mining operations, particularly in gold and copper extraction. Cyanide is the most widely known leaching agent used to dissolve gold from ore, although its toxicity raises environmental and safety concerns. To address these issues, researchers are increasingly looking for eco-friendly alternatives, such as thiosulfate or halides, that can effectively leach gold without the environmental risks associated with cyanide.
