Remediation of acid mine drainage using magnesite and its bentonite clay composite Masindi, Vhahangwele. Date: This wastewater impacts surface and subsurface water resources negatively and has to be treated before release to receiving aquatic ecosystems. Numerous wastewater treatment technologies have been developed and implemented. However, cost implications, ineffectiveness, selective treatment capabilities and generation of secondary sludge that is toxic and expensive to dispose-off to the environment due to stringent environmental regulations often limit their application. As such, mining companies are in a search for cheaper, brine free, effective and efficient mine water treatment technology. This study assessed the potential of applying mechanochemically modified cryptocrystalline magnesite-bentonite clay composite for acid mine drainage AMD treatment.

Abstract: Date is one of important products that play important role in economy and nutritional health in some tropical regions of the world. Liquid sugar of date is produced by date syrup after extraction of phases, purification, and elimination of pectin compounds, protein, fiber, and color. In this study, bleaching and clarification of keloteh variety date syrup to produce liquid sugar were investigated by response surface methodology RSM and face central composite design FCCD.

Also there are some factors such as color, ash, and absorption was determined. In low temperature and pH, the increased action of bentonite and gelatin is observed during passing the time and also high amount of impurities were removed.

Bentonite clays are widely used in a drilling operation and play a vital role as a drilling fluid. Bentonite clay mud performs several functions during the drilling operation and facilitates the drilling process. In this study, the locally available raw bentonite clays were investigated to evaluate its potential use as a mud for borehole drilling operation after its improvement with the additives. Rheological properties such as plastic viscosity, yield point and gel strength were evaluated by using a viscometer and filtrate loss test was performed by using filter press on both locally available raw bentonite clays and the commercial bentonite named as Mill gel.

From the test results obtained for the up gradation of clays with the different beneficiating materials, the drastic increase in the plastic viscosity, yield point and gel strength has been observed.

Type bentonites include those mined from the Clay Spur bed at the top of diagenesis). Neoformation of clays results from alteration by waters that post-date​.

Thus, significant radiogenic argon was retained by fine-grained detrital illite, even in shale samples very near the igneous contact.

New U-Pb zircon ages of the Sandbian (Upper Ordovician) “Big K-bentonite” in modernization of dating techniques, no new age data were added for the.

Potassium—argon dating , abbreviated K—Ar dating , is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium K into argon Ar. Potassium is a common element found in many materials, such as micas , clay minerals , tephra , and evaporites.

In these materials, the decay product 40 Ar is able to escape the liquid molten rock, but starts to accumulate when the rock solidifies recrystallizes. The amount of argon sublimation that occurs is a function of the purity of the sample, the composition of the mother material, and a number of other factors. Time since recrystallization is calculated by measuring the ratio of the amount of 40 Ar accumulated to the amount of 40 K remaining.

The long half-life of 40 K allows the method to be used to calculate the absolute age of samples older than a few thousand years. The quickly cooled lavas that make nearly ideal samples for K—Ar dating also preserve a record of the direction and intensity of the local magnetic field as the sample cooled past the Curie temperature of iron. The geomagnetic polarity time scale was calibrated largely using K—Ar dating.

The invention belongs to the production method of cat litter, particularly the production method of a kind of broken bentonite clay particle cat. Along with the raising of people’s living standard, life interest and hobby also constantly increase, and in city, the pet such as cat and dog got more and more in the last few years, and the ight soil of pet is to environment, and people are very dislikes. Cat litter is exactly a kind of product of process pet dung, and cat litter product was without definite shape in the past, and intensity is low, and dust is large, and antibiotic property is undesirable, and eliminate the unusual smell difference, is not easy to cleaning.

The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of cat litter particle balling preparation shape, intensity is high, and dust is little, and antibiotic property is good, eliminates the unusual smell, and is convenient to the production method of the broken bentonite clay particle cat litter cleared up. The technical scheme that technical solution problem of the present invention adopts is: a kind of production method of broken bentonite clay particle cat litter, comprises by bentonite parts, 20 parts, sodium carbonate, tapioca 10 parts, antibacterial agent 10 parts, waterglass 40 parts and parts, water; It is characterized in that the production method of broken bentonite clay particle cat litter is:.
