Silver Ore Synthesis

It is estimated that throughout human history approximately 50 billion ounces of silver have been mined. This volume of all time silver mined put would fit into a 52 meter cube.

Put approximately 9-10(g) copper ore into beaker. Use spatula to break up any large pieces. Next add 17ml H2SO4 (aq) (hydro sulfuric acid) to the beaker. Began mixing until all or most traces of blue dissipate; or the copper ore will no longer dissolve (should appear as a milky liquid). Next use pipette to and remove solution and divide solution into 2 individual test tubes then Place test tubes into centrifuge and run centrifuge for 1 minute. Remove from centrifuge machine Fill a cuvette with the clear solution from the test tube making sure not to disturb the sediment at the bottom. Note the solution should bluish in tint Final place the cuvette in the colorimeter. Then record data and calculate in results section.

How would you prove the silver nitrate is present in your system of copper pipes? The presence of silver nitrate (AgNO3) in your water system can be proven by taking a sample of water from your system and adding sodium chloride (NaCl). The reaction that would occur from adding sodium chloride to silver nitrate would form a precipitate, as seen below. The chemical formula for this reaction is:

Copper ore contains approximately 0.5% copper and 99.5% unwanted rock. To help separate the mineral copper from the gangue (sand, rock and other impurities), the ore is crushed and ground to a fine powder form ball mills (0.3mm particle size). Concentrating the ore (froth floatation) This is the step in which there is the separation of the mineral is and the gangue. Milled ore is then mixed with collectors i.e. water, detergent, and oils.

Silver is a chemical element with the symbol Ag, which comes from the Latin name "Argentum".

The purity of the ingredients is essential for making true colloidal silver, for impurities will transform the solution into a different substance. Even the minerals in spring water will undergo unpredictable chemical transformations,

4- Then I had to add 10 grams of the alum to the 250mL beaker that has the contaminated water,

158 50280 purification system with purity of 18.2 MΩ) and once with filtered seawater before each

The only elements that were not found in this process was gold and silver. These two metals were known since ancient times. If they were to use aqua regia, then the pure substances of gold and silver would be extracted from the ore.

Extraction is a key part of the copper production process. There are 3 different techniques that mining companies use to extract copper ore. The choice of method is dependent on many factors, including: depth and grade of the ore body, overall reserves, topography and location to name a few.

Silver compounds were used in external preparations as disinfectants, including both silver nitrate and silver proteins, which can be used in dilute solution as a drop to prevent conjunctivitis in neonates. Silver nitrate is also sometimes used as a treatment for certain skin diseases in the solid image as a caustic agent for the treatment of certain skin diseases such as corn and pimples. Silver is also used in prostheses, reconstructive orthopedic surgery and heart organs. Silver duramine fluoride appears to be an effective factor in reducing dental caries. Silver acetate is used as an aid to help quit smoking

It is expected that the following compounds will form precipitates Silver Sulphate, Copper Hydroxide, Copper Iodide, Silver Hydroxide, Silver Iodide, Cobalt Hydroxide and two Silver Chlorides. This was worked out

In “Part 3: Preparing Copper (II) solutions of Different Concentrations”, 20.0 mL of a 0.500 M solution was from CuSO4 * 5H2 O was made. The solid was weighted and was added to the 100 mL beaker. About 15 mL of water was added to the same beaker. The mixture was transferred back and forth between the graduated cylinder and a beaker to dissolve all the crystals. The solution was transferred back to the graduated cylinder. The beaker was rinsed well with a small amount of distilled water and the rinsed solution was transferred to the same cylinder containing the dissolved solid. After adding the solution, the total volume in the cylinder was about less than 20 mL. With the use of the Pasteur pipette, the water was added until the volume in the cylinder was 20 mL. This was the first solution.

First, 2 liters of water was boiled. Two hundred grams of alum was dissolved to the water while constantly stirring. After this, more alum was added to the mixture while constantly stirring until the solution can no

Dilute the colloid in a 2ml of the gold solution to 10ml of distilled water, and
