Clays heated to 450°C bleached better than those activated at 250°C and 350°C. Heatactivated clays show more bleaching power than naturally active clays and because the selective bleaching of natural clays disappears with heating, the results are predictable. Table 8—Results of bleaching with heatactivated clays.

· 1. Introduction. Bleaching earth plays a crucial role in the manufacture of edible palm oil from crude palm oil (CPO). The bleaching earth (BE) is used as the agent in the bleaching process to remove the colorant compounds contained in CPO, which is mainly α and βcarotenes (Ng and Choo, 2016; Ribeiro et al., 2018).The removal of the colorant compound .
FOOD TECHNOLOGY FACT SHEET
high value oils and recovery of oil from spent bleaching clay are carried out in batch extractors. A rotating drum and a vertical cylindrical kettle equipped with a vapor tight cover and a low speed agitator are two popular batch type extractor designs. Use of largescale continuous processes began in the early 1920s.

Heap leaching
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

A study of bleach clay solubility
STUDY OF BLEACH CLAY SOLUBILITY. 349 The acid attacking a bleach clay is never all used up even with insufficient acid (excess clay) and long continued diges tion. For leaching to proceed, there must be sufficient free acid remaining in solution to overbalance the acid silica left openbonded by the loss of some of the bases.
