Study on Activated Carbon and Gold Recovery

Since the early days of 1920 large-scale activated carbon production in the large-scale activated carbon has steadily increased in importance to industry. Continual improvement and optimization of production processes and new raw materials have led to the advanced level of adsorption technology in use today Activated carbon lies at the heart of a number of different processes used in the industry. Environmental problems affecting air and water are solved through the use of activated carbon, and new applications are being continually developed in rapid succession. Of particular interest in the field of environmental protection is the reactivation and subsequent reuse of spent activated carbon and the recycling of activated carbon that is no longer amenable to regeneration or reactivation Granular activated carbon is a specific preparation of activated carbon, or activated charcoal. It has been used as a purification agent since antiquity. Activated carbon was used for drinking water filtration in ancient India, and as a multi-use purifier in ancient Egypt. In modern times, it was introduced to Europes sugar refining industry in the early 19th century. Today, activated carbon in various forms, including granular, is used in a wide range of industrial, commercial, and home applications to remove contaminants.
