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)

November 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

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

Coursework 4 Copper Name of student: Alfiya Ospanova Tutorial group: G Copper is one of the earliest elements explored by humanity. Due to the special red shade it was easy to find in ancient times. The metal was named according to place where it was found‚ the Cyprus islands. Copper produced in massive stars and spread in the world as minerals like chalcocite and chalcopyrite (sulfide of copper)‚ azurite and malachite (carbonate of copper)‚ cuprite (oxide of copper). The atomic

In this lab‚ we changed copper into various forms using different chemicals and chemical reactions. The purpose of this lab is to demonstrate that the product of a chemical reaction depends on what is present at the time of that reaction. This lab also displays how matter cannot be created nor destroyed in a chemical reaction. In a lab‚ you must always make safety a priority in case of an emergency. In our lab‚ we made sure to wear closed-toed shoes as well as goggles at all times. We also performed

9/15/11 AP Chemistry Dr. Isotone Lab 1: Determination of the Empirical Formula of Silver Oxide Lab Objective: In this experiment‚ the percent composition and empirical formula of silver oxide will be determined. Silver oxide will be heated until it decomposes to silver metal and oxygen‚ and the percent calculation and empirical formula can be calculated based on combining the ratios of silver and oxygen in the reaction. Summary of Lab Procedure: 1. Set up Bunsen burner on
