Kiwi :

The world's largest consumption of the first 26 kinds of fruit, kiwi is the most comprehensive. The content of Vc, Mg and trace elements in kiwifruit fruit was the highest. Among the top three low-sodium and high-potassium fruits, kiwi is at the top of the list because it contains more potassium than bananas and citrus. At the same time, the content of Ve and Vk in kiwifruit was determined to be excellent, low in fat and no cholesterol. According to the analysis, kiwi fruit vitamin content per 100 grams of fresh samples in general 100-200 mg, high up to 400 mg, about 5-10 times the citrus; sugar 8-14%, acid 1.4-2- 0%, but also with tyrosine and other amino acids 12 species.

kiwi fruit contains a wide range of nutrients, most of the fruit is rich in one or two nutrients, but each kiwi can provide 8% DV folic acid, 8% DV copper, 8% pantothenic acid, 6% Fresh, 4% DV iron and vitamin B6, 2% DV phosphorus and Va as well as other vitamins and minerals. Kiwi in addition to kiwi alkali, proteolytic enzymes, tannin pectin and sugar and other organic matter, as well as calcium, potassium, selenium, zinc, germanium and other trace elements and the human body needs 17 kinds of amino acids, but also rich in vitamins, , Fructose, citric acid, malic acid, fat.

A kiwi can provide a day more than twice the demand for vitamin C, known as the "king of fruit." Kiwi also contains good soluble dietary fiber, as the fruit of the most eye-catching place is contained in its superior antioxidant properties of plant chemical substances sod, according to the US Department of Agriculture research report, kiwi comprehensive antioxidant index in the Fruits among the top, second only to the thorns, blueberries and other small fruit, far stronger than apples, pears, watermelon, citrus and other daily fruits. And blueberries belong to the second generation of fruit is quite representative.

Raw Bauxite:

Bauxite is a soft, whitish to reddish-brown rock consisting mainly of alumina-bearing hydroxides, oxides of iron, silicon and titanium with impurities of Ca, Mg, Cr, V, P, Ga and other elements. Raw Bauxite is a major source of aluminium. Basic alumina containing minerals of Bauxites are gibbsite Al(OH)3, Boehmite g-AlO(OH) and Diaspore a-AlO(OH). We are a major Raw Bauxite Exporter based in Maharashtra (India) and catering to the diverse demands of several middle and eastern Asian countries.

About Raw Bauxite:
The processing of Raw Bauxite is done at a number of alumina refineries in the world. Bauxite can be processed at a low-temperature autoclave digestion (145 oC to 155 oC). Raw Bauxite can be used also for sweetening stage and for non-autoclave digestion in agitators (105 oC).

About 85% of bauxite mined worldwide is used to produce alumina for refining into Aluminium metal and the balance 15% is processed and value added to make its way to other uses like refractory, chemical, cement, abrasives, etc. Aluminium is possibly the most versatile product with applications in almost every industry. Since Bauxite is the primary source for Aluminium there will always be an ongoing promising demand for the same.

Application & Uses of Bauxite:
Raw Bauxite is successfully used for metallurgical grade alumina production besides applications in the cement industry, alumina chemical, steel, alum, energy industries, flame-retardants, etc. Bauxite is used in :
- Aluminium
- Cement
- Chemical
- Blast Furnaces
- Iron/Steel Ladles, etc.

Advantages of Artha Bauxite:
Artha Mineral Resources has good sources for Gibbsitic Bauxite which requires low digestion temperature (145 oC -155 oC) making it more economical to process. Mines are also in close proximity to all-weather ports which makes it very convenient and cost effective to ship this material.
