There are four major factors that often contribute to the formation of hydrothermal copper porphyry: 1) readily available mineralizing fluid solutions that dissolve and transport metals‚ 2) openings in rocks which allow permeable flow of hydrothermal fluids and the metals that they transport in solution‚ 3) available sites within the fractured rocks which allow for deposition of the minerals from solution‚ and 4) the requisite chemical reactions that contribute to that deposition (Bateman‚ 1967)

HEAT TREATMENT OF COPPER AND COPPER ALLOYS COPPER AND COPPER ALLOYS: Copper and its alloys are widely used in many products that are used in our everyday life. They have excellent properties such as electrical and thermal conductivity good strength. They have high corrosion resistance and fatigue resistance. Copper is a non-magnetic material. Pure Copper is soft and used widely in wires and cables and is extensively used for passage of electricity. Copper is used in the building construction.

Estimating Osmolarity by Change in Weight By: Sondus Kahil 27 February 2012 TA- Ashley Hintz Biology 200A-section 002 Abstract: My group and I conducted the experiment that estimates osmolarity by change in weight of potato tubers‚ this was conducted in order to explore the process of diffusion and osmosis and more importantly to investigate the question of “Does different concentrations of sucrose solutions have an effect on the final weight for the potato

Copper is an element that occurs in minor amounts in the earth’s crust. Estimates of average crustal prevalence are on the order of 0.0058 percent by weight. Deposits considered to be economically recoverable at current market prices may contain as little as 0.5 percent of copper or less‚ depending on the mining method‚ total reserves‚ and the geologic setting of the deposit. Here is the flow sheet on how to process copper from Zenith. Copper Process Flow Sheet: Copper ore is first quarried from

They have typical three layer blood vessel wall structure with a thick tunica media. The walls of arteries are highly compliant due to the elastic fibres present. The wall thickness of the arteries varies in based on the proximity to the heart. The elasticity of arteries allows pressure absorption from the left ventricle of the heart as it pumps blood into the arteries. There are two significant types of arteries‚ elastic and muscular. Elastic arteries are the largest in the body and include the aorta

3rd‚ 2009 Lab Report #3: Copper Cycle Abstract: The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle‚ copper was present in different forms. First reaction involves reaction between the copper and nitric acid‚ and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into copper 2 oxide and water when heated

Rocks containing copper compounds (such as copper carbonate) are called ‘copper ore’. Copper is extracted from copper ore by a series of chemical‚ physical‚ and electrochemical processes. Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain. After mining‚ the ore is crushed‚ roasted‚ smelted and then electrolysed to extract the copper. Suggested Equipment Boiling tube Samples of different carbonate ores‚ containing

The Effect of pH Level of a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron
