Extractive Metallurgy Minerals are naturally occurring chemical substances in the earth’s crust obtainable by mining. Out of many minerals in which a metal may be found‚ only a few are viable to be used as sources of that metal. Such minerals are known as ores. Examples: Galena‚ PbS‚ etc. It is usually contaminated with earthly or undesired materials known as gangue. The extraction and isolation of metals from ores involve the following major steps: • Concentration of the ore‚ • Isolation of the

CASE STUDY 1: Xstrata Produced Acidic Oxide – SULFUR DIOXIDE Industrial Process – Sulfur Dioxide is an acidic oxide produced domestically and industrially in many ways. Xstrata‚ particularly Mount Isa Mines LTD‚ produces sulfur dioxide as a by-product from the extraction of copper from ores. Copper ore mined in Australia is predominantly chalcopyrite (CuFeS2)‚ a sulfide ore of copper. The extraction of copper begins with crushing the ore and subjecting the crushed ore to froth floatation. In

Schmoe Period 3 March 8‚ 2013 Lab Report: Empirical Formula of Zinc Chloride (ZnCl) * Purpose The purpose of this experiment was to learn how to determine the empirical formula. Empirical means “based on experimental evidence.” * Experimental Design The reaction that occurred was the reaction of the elements Zinc (Zn) and Chloride (Cl) by mixing a piece(s) of Zinc and 50mL of Hydrochloric Acid (HCl). The amount of Zinc was determined to be between 1.00g and 1.25g. As the reaction occurred

Introduction of Lab 5: Analysis of a Zinc: Aluminum Alloy The analysis of a metal alloy was designed to learn how to use the Ideal Gas Law (formulas listed below) in a laboratory setting in relevance to acquiring moles of gas created‚ thus giving us one step closer to finding the molar mass. The importance of the Ideal Gas Law‚ as well as the other gas laws‚ is that it signifies the relationship between the properties of an ideal gas. These properties assist in the explanation of the Kinetic Molecular

concentration of Zn2+(aq) ions (0.2‚ 0.4‚ 0.6‚ 0.8‚ 1.0) (moldm-3) affect the voltage (V) of the voltaic cell consisting of Zinc and Copper half cells? Aim To see the relationship between increasing the concentration of Zinc ions and the voltage that is obtained from voltaic cell. The concentration of zinc ions can be directly manipulated by changing the concentration of a zinc sulphate aqueous solution‚ and the voltage will be measured using an electronic voltmeter. Background Information A voltaic

I have a lot ofslime recipes listed. As written‚ these instructions make a clear slime that glows in the dark. However‚ you could add zinc sulfide to any of the recipes for slime with different characteristics. 2. The slime is made by preparing two separate solutions‚ which are then mixed. You

determination of an enthalpy change using Hess’ Law. The temperature can be measured manually but this experiment is ideal for using a data logger. In the first experiment we are trying to determine delta H for the reaction of zinc with Copper 2 sulfate producing copper and zinc sulfate. How would I solve for delta H? In the second experiment we are trying to determine delta H for the hydration of anhydrous copper 2 sulfate. If anhydrous copper 2 sulfate powder is left in the atmosphere slowly absorbs

Zinc Reacts with Vinegar’s Acetic Acid To Produce Electricity March 7‚ 2014 Abstract This research is about the chemical reaction of zinc with acetic acid to produce a short amount of electricity. Even though it only conducts a small amount of voltage‚ we investigated and experimented on how it can produce more than usual without adding any other components on the project except zinc‚ copper‚ vinegar‚ or a unique container that can increase the voltage of our product. The zinc can produce
