Mercury mineral extraction with

TLC has been used for the identification of heavy metals in aquatic plants. For this purpose, plants were mineralized with cone. H2SO4, HNO3, and HjOj, extracted with water, derivatized with dithizone, and chromatographed. The identified metals were zinc, copper, mercury, and lead [31]. [Pg.361]

In the Wet Work, the best solvent for separating the essentials is the Mercury of the particular kingdom. In the work on plants we used a Vegetable Mercury to extract or separate our three essentials. We can proceed in the same way with the Mineral and metals work by using the correct type of solvent for the work at hand. [Pg.73]

For the determination of total mercury, the samples were mineralized by microwave digestion using nitric acid. The final determination was performed by CVAAS. Methylmercury was determined by CGC/ECD after extraction of 0.2 g fish powder in toluene, back extraction with a cysteine acetate solution and further extraction with toluene. Calibrations were performed by standard additions. The uncertainties of the methods of final determination were assessed by the analysis of 10 aliquots from one digest solution (nitric acid for total mercury, toluene for methylmercury). The CV of the method, therefore, does not comprise the CV introduced by the extraction procedure. [Pg.57]

Arsenic is sometimes found in nature in native state and is fairly easily extracted from its compounds. It is not known who was the first to produce elemental arsenic. Usually its discovery is ascribed to the alchemist Albert the Great. Paracelsus described the process of preparing metallic arsenic by the calcination of arsenic with egg-shells. According to some reports, metallic arsenic was known much earlier but it was considered to be a variety of native mercury. This is due to the fact that arsenic sulphide resembles one of mercury minerals and the extraction of arsenic from its ores is rather simple. [Pg.39]

Approximately 75% of all elements found on and in the Earth are metals. They are crystalline solids that at room temperature range from hard to butter-like soft to liquid (mercury). They are generally good conductors of heat and electricity as a result of the swarm of relatively free electrons in their outer shell that move without much resistance to other elements, particularly those with a dearth of electrons in their outer shells. In pure states, most metals have a shiny luster when cut. Those located at the far left of the table have only one electron in their outer shell. Therefore, they are very reactive and are not usually found in pure form. Instead, they are found in compounds, minerals, or ores that must be processed to extract the pure metal from the other elements in the compounds. [Pg.36]

Few metals occur in the earth s crust uncombined with others. Those that do, such as gold, silver, mercury, and some copper, are known as the native metals. Together with some native nonmetals such as carbon and sulfur, the native metals make up the relatively small group of native elements, naf-urally occurring masses of single elements that were recognized and put to use by humans in quite early times. Most metals occur in nature combined with nonmetals in the form of mineral and rock deposits, and from fhose minerals they are extracted by means of a variety of metallurgical fechniques. [Pg.158]

Extraction.—(1) From Pyrites.—In the oxidation of the pyrites (or other sulphur mineral) for the formation of sulphur dioxide in the manufacture of sulphuric acid, foreign elements like arsenic and selenium also undergo oxidation and pass ofC as vapours with the sulphur dioxide. The selenium dioxide produced in this manner their suffers more or less complete reduction by the sulphur dioxide, when finely divided selenium separates, mainly in the lead chambers, as a red, amorphous powder, accompanied possibly by some of the greyish-black form a portion of the dioxide is also found in the Glover tower acid. The amount of selenium in the chamber mud depends, of course, on the nature of the pyrites relatively large quantities of compounds of arsenic, zinc, tin, lead, iron, copper or mercury are always present, arising almost entirely from impurities in the pyrites. [Pg.287]

FUMUS — is the Scoria, an incrustation on the floor, yet properly that which arises and brings the body with it. For there are two kinds of smoke, which mix with the earth, make the stars fall from heaven, make also comets and rainbows about the sun and moon. When the batia finds a mineral matter, then it is to the smallest extent mingled with it. It also becomes fixed and a metal, but should the batia not find any, then it becomes a mercury but the mineral power which it ought to find is clear sulphur washed, and partially fixed, and it is found in the extracted stones, and in sand. It shines like silver, and because nothing can be produced without this, it is found in every place... [Pg.140]

EMERALD OF THE PHILOSOPHERS — A name which has been given to the Flos Coeli, and sometimes to the Dew of May and of September. The last is looked upon as masculine because it is more cocted and digested by the warmth of the summer. The other is considered female because it is colder, cruder, and more akin to winter in its quality. Some chemists, understanding these words literally, have imagined that dew was the matter from which the Philosophers extracted their mercury, because they often say in their books that mercury is male and female. So they have deemed that the union of the Dew of May with that of September would constitute that marriage so recommended by true chemists. But they should have noticed that the matter of their mercury must be mineral because the ox will produce but the ox, the apple an apple only, and it is an egregious blunder to suppose that any metal can ever be produced from a tree or a plant. [Pg.315]

From your extraction the oily substance is a combination of Mercury and Sulphur, the ashes from the remaining herb (which is calcined) is the Salt. The Sulphur can be separated from the Mercury by further distillation, but in herbal alchemy this further separation is not as essential as in mineral alchemy. In the forming of the alchemical spagyric medicine or elixir, the oil extract and the final product of the ashes are joined. But for other uses, i.e. oils and incense, the combinations vary along with any points of conjunction necessary in the recipe. All in all, the end result is the same—where Sulphur, Salt and Mercury make up the final product. [Pg.91]

And Basil Valentine in the Stone of Fire is almost equally explicit. "All metals and minerals have one root from whence their descent is he that knows rightly needs not to destroy metals in order to extract the spirit from one, the sulphur from another, or the salt from another for there is a nearer place yet in which these three, namely the mercury, salt and sulphur—spirit, soul and body—lie hid together in one thing, well known, and whence they may with great praise be gotten."... [Pg.43]

With regard to geochemical cycling (as well as for economic considerations), it is important to distinguish between the abundance of an element and its availability. The availability of an element is related not only to its relative abundance on Earth but also the stability of minerals in which it is a major constituent. Thus, a number of elements (e.g. copper, mercury, tin, and arsenic) that are scarce in terms of their average crustal abundance are easily isolated due to their ability to form mineral deposits. The most unavailable elements are those that form no major minerals of their own. Many of the rarer elements are available for economic use only to the extent that they are obtained as byproducts of the extraction of more abundant elements. Tellurium, for example, is produced during the electrolytic refining of copper. [Pg.318]
