The invention relates to a method for extracting curcumin from turmeric. The method is characterized by comprising the following steps that: the turmeric is cleanly cleaned and is then crushed into turmeric powder, the turmeric powder and extraction solvents are mixed according to a certain proportion and are then subjected to backflow extraction, next, the separation is carried out under

03-09-2015Rapid industrialisation is contributing to water pollution. There is a need to identify cheaper and efficient methods of removing contaminants as the demand for clean water rises. A study is carried out to investigate the extraction of alum from locally abundant kaolin clays using sulphuric acid. Alum is a coagulant that is used for water treatment.
In the HCl-clay process, kaolin is cal- cined to an amorphous mixture of alumina and silica, The calcined kaolin is leached with HC1 solution, and aluminum is dissolved according to the following reaction: The Al.C13 solution is evaporated or sparged with HC1 gas, and the solid, A1C13*6H20, is formed.
In 1981 Freeport Kaolin started producing premium brightness kaolin products based on the patented process Young et al., 1985 named Titanium Removal/Extraction Process or "TREP". In 1985 Freeport Kaolin was acquired by Engelhard Corporation who continues to use this process as well as the older Ultraflotation technique.
This paper studies the extraction of aluminium from kaolin through leaching process, using aqueous solutions of acids and bases, as leaching agents. For this study, crude kaolin excavated in Milos Island, Greece, was used.
SbE pretreatment decreased cisplatin-induced kaolin intake in the rat model of simulated nausea, suggesting that SbE and its active constituent s may play a therapeutic role in chemotherapy-induced emesis. Absence of therapeutic effect at the highest tested SbE dose could have been a result of proo
25-04-2017The process of extracting kaolin begins with geologists during research to identify land with potential kaolin deposits. Once a piece of land is deemed to have potential, kaolin holes must be drilled around the area to get core samples of the earth to send back to laboratories to determine the quality and size of the kaolin deposit.
The optimum conditions for the Al recovery from the studied kaolin include the grinding and screening of kaolin to particles size below 90 μm, calcination of kaolin at 850 o C for 2 hours, leaching with 6 M HCl with the solid/liquid ratio of 0.1 g/ml for 3 hours at 90 o C and 500 rpm in a reflux system. The percent of aluminum recovery from calcined kaolin under the studied conditions reaches about 75 wt%.Cited by: 4
Sep 01, 2018Raw coal-series kaolin samples were calcined at different temperature, and then were respectively leached by hydrochloric acid solution 15 wt%, L/S ratio of 10 cm 3 /g at 200 & 176;C for 60 min. The influence of calcination temperature on extraction rate of Al is shown in Fig. 1.Between 600 & 176;C and 800 & 176;C, the extraction rate of Al increases from 53.6% to 98.6% with calcination temperature, butCited by: 14
09-12-2020Highlights. The Kaolin 0.9 release include a reformat of the API and various improvment of the performance and the ergonomy of Kaolin. A reformat was required to be able to have a maintainable, clean and reliable Kaolin in the long term.
Aluminum MakingDiffrent Alumina Extraction ProcessesHigh Temperature ProcesesSee AlsoLinksAluminum making needs huge amount electricity 15kwh/kg , some carbon source to smelter electrodes, little fluoride to lower melting point and lot of pure alumina Al2O3 . It is known Hall process en.wikipedia.org/wiki/Hall process. There are no other more economical process. Key material to aluminum is ultra pure alumina and cheap energy. There are many process to make pure alumina, we should select some best fit to small scale production. Clays are posible start material or feldspar minera
The invention discloses a method for extracting menotrophin from urine of postmenopausal women by use of a kaolin adsorption method. The menotrophin is easily participated and separated out by adjusting the pH value of the urine in the kaolin adsorption procedure by using the characteristic that menotrophin protein is the lowest in solubility at an isoelectric point.
kaolin soil spiked with known concentration of phenan-threne and nickel. These tests helped to assess the capa-bility of using different types of extracting solutions such as surfactants, cosolvents, chelating agents, cyclodex-trins, and organic acids for the solubilization and removal of phenanthrene and nickel from the kaolin soil.
