Zinc History

Copper-zinc (VMS-type?) mineralized zones were discovered in Archean volcanic rocks in the southern part of North Williams Township by Metron Explorations Limited in 1970. The mineralized zone and surrounding area were evaluated with a HLEM survey and drilled with 2 DDHs (totaling 61.3 m) that did not intercept significantly mineralized rocks (Willars, 1971).

Zinc chloride is an ionic compound. An ionic compound is made up of two elements, a metal and non-metal. They also consist of positive and negative ions. When an ionic compound is formed the ions bond to make a zero charge. The second element (the non-metal) is named by adding –ide to the end of it, providing it is a monatomic ion. The mixture of zinc chloride contains a metal (zinc) and a non-metal (chloride). Zinc has a charge of +2 and Chlorine has a charge of -1, so it consists of a positive and negative ion. Thus when zinc and chlorine combine, it actually takes 2 chlorine ions to bond with 1 zinc ion. This would give the formula a zero charge, and also make it an ionic compound. Finally, the name of the non-metal ion is chlorine, in this experiment it becomes chloride, adding –ide to the end also is proof it is an ionic compound since this is a bond between a metal and non-metal, and since there is no prefix in the name.

Stability-Stable. Incompatible with amines, cadmium, sulfur, chlorinated solvents, strong acids, strong bases. Air and moisture sensitive. Zinc powder is very flammable.

Zinc, number 30 on the periodic table and a bluish-white metallic element, exists naturally in air, water and soil. It is present everywhere in the environment. All life on earth has evolved in the presence of zinc. Natural processes such as erosion, forest fires, aerosol formation above the seas and volcanic eruptions continuously transport Zinc. Zinc melts at about 420° C and boils at about 907° C. Zinc is efficient for plants. Zinc-deficient soils present in many parts of the world are a cause of low crop yields. Not only does it help plants but also the human body. It is responsible for the proper functioning of more than 300 enzymes in the human body, and is vital for the immune system. It will also fight against cold

Zinc is not just used for batteries, pennies and brass shell casings. It is also used for medicine. Interestingly it is known as an “essential trace element” for the small amounts of it necessary for human health. It was discovered by Andreas Marggraf in 1746 in Germany, after two other men (William Champion and Anton von Swab) a couple years earlier. Andreas Marggraf though, was credited for the isolation of Zinc after establishing a detailed theory for it. A reason I chose the picture of the pennies is because they are thought to be made of copper, but these days it is about 97.5% zinc inside. The brass shell casings are interesting for the reason that the brass is an alloy of copper and zinc, showing another variety of objects made of zinc.

The most common compound of zinc found in nature is zinc sulfide. In Zinc sulfide the elements are Boron, Oxygen and Zinc.

The construction of the Periodic Table of Elements was prior to the discovery of the individual elements. Elements such as silver, gold, tin, copper, lead and mercury have been known for centuries. In 1649, the first scientific discovery of an element was made by Hennig Brand when he discovered phosphorous. Prior to Brand’s discovery, chemists had acquired an immense body of understanding concerning the properties of elements and their compounds for the next 200 years.

Because in the data above I concluded that Zn is the most reactive then Fe and the finally Ni I know that Zinc will displace Iron and Iron will displace Ni but Ni will not displace Iron. Because of this if we place one piece of each metal in the solution of Iron(II) nitrate which ever one reacts is the Zinc because the Zinc will be displacing the Iron but since the Ni cant displace Iron no reaction will occur when it is placed into the Iron nitrate.

1. Ancestry Discovered in approximately 3000 BC, silver is one of the oldest elements known to man. Why was it so easy for miners in Turkey and Greece to discover, one may ask? Silver is also one of the most abundant elements found on earth and was not difficult to come across when mining mountains and rocks. (Silver, 1)

Among these transporters zrfC gene encodes a transporter for acquiring zinc from alkaline zinc-limiting media and the other two transporters, coded by genes zrfA

Based on Figure 4.6 the metals cations will enter into the pores of zeolite NaA and urged the metals alkali and alkaline earth cations which are soluble in water. In addition, zeolite NaA more selective towards the transition metals because it has larger sizes so easy dipolariasi (Auerbach, et al. 2003) Zeolite NaA tend to bind cations because the negatively charged zeolite cavities. The negative charge is derived from the framework of teteahedral alumina attracts cations are positively charged. The negative charge on NaA zeolite pores causing the occurrence of ion exchange. So in the few studies reported that the zeolite is able to reduce the levels of heavy

As discussed, Horsehead Corporation is one the top manufactures of Zinc in the US. One of the main uses of Zinc is in making protective coatings for steel and Iron. As Zinc protects iron and steel from corrosion. Though the hardness and intensity of Zinc are not so good, if combined with other metals like copper and aluminum its hardness and intensity improves significantly. Zinc alloys are used in making many components that can be used in automobiles.

Chromium doesn't naturally occur in nature as its a uncombined element, it’s usually combined with iron and oxygen in a mineral called Chromite. Chromite is found in some beach sands, caused by the weathering of chromite-bearing rocks that develop over peridotite Chromium isn’t a naturally occurring element, however the process occurs in Zimbabwe, Africa and begins by being mined by both underground and surface techniques then followed by extracting which there metallic elements are extracted

The element I am researching is Iron(Fe). Iron could be used in many ways. Iron is a ductile, gray, relatively soft metal and is a moderately good conductor of heat and electricity. 2.It is attracted by magnets and can be readily magnetized. 3. The pure metal is chemically very reactive and rusts readily in moist air, forming red-brown oxides. Rust is iron oxide and when it is hydrated, it rusts.

Mabati rolling mills need to raise funds of about 2.3 billion shillings, to include 55% of aluminum zinc to their state of the art continuous galvanizing line at Mariakani. This facility would add product diversity and would fasten the growth of the company in the competitive steel industry. Aluminum zinc in comparison with the ordinary steel coated with zinc was more durable and had a longer life span around 4 times more than the steel coated.
