Rich antimony and calamine mines are worked by a French undertaking, and good marble is quarried by an Italian company.
The most important minerals are lead and zinc, obtained in lodes in the forms of galena and calamine respectively.
Calamine chiefly occurs in Spain, Silesia and in the United States.
She didn't bring any calamine lotion because she had never broken out with poison ivy before.
Cambrian, Ordovician and Silurian beds have been recognized, the Upper Cambrian consisting of a limestone which is very rich in metalliferous ores (especially galena and calamine).
It is, however, nearly always found associated with zinc blende, and with calamine, although only in small quantities.
Galena and other lead ores are abundant in veins in the limestone, but they are now only worked on a large scale at Mill Close, near Winster; calamine, zinc blende, barytes, calcite and fluor-spar are common.
Galena and other lead ores are abundant in veins in the limestone, but they are now only worked on a large scale at Mill Close, near Winster; calamine, zinc, blende, barytes, calcite and fluor-spar are common.
The ores found here comprise silver-free galena, sulphate of zinc and calamine.
Many are found as minerals, the more important of such naturally occurring carbonates being cerussite (lead carbonate, PbC03), malachite and azurite (both basic copper carbonates), calamine (zinc carbonate, ZnCO 3), witherite (barium carbonate, BaCO 3), strontianite (strontium carbonate, SrC03), calcite (calcium carbonate, CaC03), dolomite (calcium magnesium carbonate, CaCO 3 MgCO 3), and sodium carbonate, Na 2 CO 3.
From his account it is quite clear that that metal was zinc, but he did not recognize it as the metal of calamine.
Second in importance is the carbonate, calamine (q.v.) or zinc spar, which at one time was the principal ore; it almost invariably contains the carbonates of cadmium, iron, manganese, magnesium and calcium, and may be contaminated with clay, oxides of iron, galena and calcite; "white calamine" owes its colour to much clay; "red calamine" to admixed iron and manganese oxides.
Of less importance is the silicate, Zn 2 SiO 4 H 2 0, named electric calamine or hemimorphite; this occurs in quantity in Altenburg near Aix-laChapelle, Sardinia, Spain and the United States (New Jersey, Pennsylvania, Missouri, Wisconsin).
Oxide of zinc, like most heavy metallic oxides, is easily reduced to the metallic state by heating it to redness with charcoal; pure red zinc ore may be treated directly; and the same might be done with pure calamine of any kind, because the carbon dioxide of the zinc carbonate goes off below redness and the silica of zinc silicate only retards, but does not prevent, the reducing action of the charcoal.
The charge of the retorts consists of a mixture of 1100 lb of roasted calamine and 550 lb of dry powdered coal per furnace.
Zinc carbonate, ZnCO 3, occurs in nature as the mineral calamine (q.v.), but has never been prepared artificially, basic carbonates, ZnCO 3 .xZn(OH) 2, where x is variable, being obtained by precipitating a solution of the sulphate or chloride with sodium carbonate.
- Coal has been discovered in the Khmir ("Kroumir") country, but the principal mines at present worked in Tunisia are those of copper, lead and zinc. Zinc is chiefly found in the form of calamine.
It also enters (as carbonates) into the composition of many minerals, such as chalk, dolomite, calcite, witherite, calamine and spathic iron ore.
It is a constituent of the minerals cerussite, malachite, azurite, spathic iron ore, calamine, strontianite, witherite, calcite aragonite, limestone, &c. It may be prepared by burning carbon in excess of air or oxygen, by the direct decomposition of many carbonates by heat, and by the decomposition of carbonates with mineral acids, M2C03+2HC1=2MCl-FH 2 O+CO 2.
Algeria is rich in minerals, found chiefly in the department of Constantine, where iron, lead and zinc, copper, calamine, antimony and mercury mines are worked.
In 1853 works were established for the manufacture of white oxide of zinc from a calamine found here, in the next year metallic zinc was produced, and in 1865 the first sheet zinc made in America was rolled here.
flatly discovered the same property in the Siberian and Brazilian topaz, borate of magnesia, mesotype, prehnite, sphene and calamine.
The lead ores are galena and carbonate; the zinc ores, calamine, smithsonite and blende.
calamine mining industry in Shipham and Rowberrow were poorly understood.
calamine cream or 1% hydrocortisone available from a pharmacist will relieve the itching.
Calamine lotion will relieve the irritation whilst paracetamol will also help.
For heat rash, sponge baby with cool water, pat her dry, then apply calamine lotion.
Mild inflammation and itching can be relieved with antihistamine drugs or calamine lotion, zinc oxide, or other mild lubricants or anti-itching creams.
Aspirin and other pain medications, oral antihistamines, and calamine lotion are good for treating minor symptoms.
Treatments for the itching of poison ivy, oak, or sumac rashes range from calamine lotion and oatmeal baths to over-the-counter antihistamines and topical creams.
Calamine lotion and menthol ointments lessen the itching and dry out weeping blisters.
Calamine lotion (and some other kinds of lotions) also reduces itchiness.
Itching can be lessened by the use of calamine lotion or antihistamine medications.
Calamine lotion applied to affected skin can reduce irritation somewhat, as can cold-water compresses.
Things you may already have in your medicine cabinet to treat poison ivy, oak, or sumac include calamine lotion, Noxzema, rubbing alcohol, and Milk of Magnesia.
A topical skin product such as Calamine may treat the condition effectively and reduce the discomfort.
Calamine lotion is recommended for itchy skin.
Calamine Lotion - Available in that familiar pink bottle, calamine lotion can prevent the incessant itching that often comes with sunburned skin.
