Sorting/Processing of waste. Depending on the nature of the source material, there are a plethora of sorting and processing activities utilised that range from labour intensive hand picking operations through to highly mechanised or technically complex processes. The chosen method of sorting will depend on many factors such as the nature of the waste, the ease of segregation and the yield and ...

The primarily used equipment in crushing are-jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy intensive.

The extent of processing differ greatly from plant to plant, and there is considerable variation in the volume and composi- tion of the waste water generated. It is often possible to make significant reductions in polluting load by good housekeeping within the factory or by modification of the processes, particular by separately recovering blood and paunches. However, these waste waters behave ...

After being transported to the processing plant, the wet sand and gravel raw feed is stockpiled or emptied directly into a hopper, which typically is covered with a "grizzly" of parallel bars to screen out large cobbles and boulders. From the hopper, the material is transported to fixed or vibrating scalping ...

Vermicasting, also called vermicomposting, is the processing of organic wastes through earthworms . It is a natural, odourless, aerobic process, much different from traditional composting. Earthworms ingest waste then excrete casts – dark, odourless, nutrient- and organically rich, soil mud granules that make an excellent soil conditioner. Earthworm casts are a ready-to-use fertilizer that ...

Also known as TOWN GAS WORKS, these plants used a coal gasification process to manufacture fuel gas for lighting and heating. The by-product produced was a gas-processing residue. Many of these facilities generated large volumes of waste oil residues commonly referred to as COAL TARS which were buried in waste pits on-site and remained after the plants closed. Chemically, they primarily ...

The separation of mineral from gangue is called mineral processing. Often times, inefficient processing methods can produce gangue that still holds an ample amount of valuable minerals. As values of minerals increase, it can even be profitable to reprocess gangue to extract additional minerals that may have been missed during the first processing.

For example, our API manufacturing plant at Quality Road in Singapore replaced the chemical process used to manufacture the antibiotic, amoxicillin, with a process that uses a biology-based technology using enzymes. The enzymatic process replaces organic solvents with water, so almost 80% of the chemical waste associated with older chemical processes has been removed. The new process …
