Alum Crystals: Synthesis Of Aluminum

* Plants can remove metals from low grade ores. The metal can be recovered by processing the ash from burning the plants.

We packed the powdered alum into a capillary then dropped it onto the lab table to make it move to the bottom. My group then strapped the tube onto a thermometer using a rubber band. Next, we clamped the thermometer with the capillary tube onto a ring stand with a rubber stopper. We dipped the thermometer and tube into a Thiele melting point tube that held silicon oil inside of it. My group heated the tube with a bunsen burner and waited for the powdered alum to melt from the capillary tube. We recorded the temperature at which the alum disappeared from the tube to get our melting point. This whole process was repeated to find a more accurate melting point than the first

Copper is formed by the melting and cooling of molten rock and found fairly close to the Earths’ surface, alongside with silver it has sulphite within the ores as they are created in brine which is a boiling salty water deep within the Earths’ crust and then pushed up through ocean vents and create a chimney like effect. Gold is formed through Hydrothermal-hot water-fluids of which are extremely rich in sulphur and found generally near or in

To find the unknown #8 Alkaline I realized that the only anion that had 4 distinct precipitate reactions for each alkaline was H2SO4, so all I had to do was react Unknown #8 with H2SO4. I did this experiment and the reactant was milky white. Based on this reaction in comparison to my previous reactions I concluded that unknown #8 alkaline was the alkaline earth Ba. This experiment was most efficient because it only took one step to figure out what my unknown was, since their was four different reaction outcomes and four different earth metal each matching to one out come this was clearly the most efficient way.

Aluminium is mined on the surface of the crust. The extraction is done by electrolysis. Aluminium oxide has a high melting point at over 2 000°C, as a result it is expensive to melt it, so, it is dissolved in molten cryolite.

There are two types of minerals that we find in Earth - rock-forming and ore minerals.

Barium is a soft silver that is alkaline earth metal. Barium is never found in nature as a free element. The two of the most commonly natural occurring minerals of barium are as followed: barite, and witherite, they both very insoluble in water . Barium was soon identified as a new element back in 1774. Barium ended up not being reduced until 1808. Barium was beginning to be used as a “getter” for different vacuum tubes. Many barium compounds are added to fireworks so that the green color of fireworks can be seen. Barium is to be known as a insoluble additive to many oil wells and drilling fluids. The soluble barium ion and soluble compounds are extremely poisonous,

One of the biggest challenges facing the world today is the shortage of fossil fuels for energy production. Finding solutions to energy production that can be man made will benefit future generations and improve the quality of life in our country as well as the lives of those abroad. In America we use the greatest amount of energy per person of any country in the world. Even though we have tried to cut energy consumption and greenhouse gas emmission since the 1990’s we have steadily increased use. Since it is becoming more and more clear that American refuse to forgo creature comforts in order to help restore the environment we must find alternative energy sources that do not pollute the environment. Chemistry can provide

Lithium does not occur as a metal in nature. It is found in small amounts in nearly all igneous rocks and in waters of many mineral springs. For many years lithium was extracted from mineral ore. More recently the metal is extracted from lithium containing brines. Brines are underground reservoirs that contain high concentrations of dissolved salts such as ;lithium, potassium and sodium

Alkaline Earth Metals are Metallic elements found in the second group of the periodic table. All alkaline earth elements have an oxidation of +2, which makes them highly reactive. All of the discovered Alkaline Earth metals occur in nature. The properties of this metal are all silvered colored, soft, and

Metalliferous rocks contain metal-bearing minerals in large enough quantities that the metal can be extracted economically. (Nordic Minning, n.d.)

Approximately 40% of the world supply of bauxite comes from Australia a stable political, economic and social system with aluminium broad application thereby, aluminium supply will have long – term positive impact, and

When alum is added to water it undergoes the reaction below. The alum reacts with bicarbonate to form aluminum hydroxide, a precipitate. The coagulation reactions are as follows:

Iron is part of the most found elements in the earth. Around 5.6% of the earth’s crust has been composed of it, and almost the entire core of the earth. In addition, Iron has been discovered about 5000 years ago, and the name comes from the Scandinavian word “iarn”. [1]

You may not have realized this but aluminum can be found widely throughout daily life. In fact, it’s the most abundant metal in the earth 's crust. Aluminum is used to make food and beverage cans, pots and pans, airplanes, siding and roofing, foil and a variety of consumer products such as:
