Nickel lateritic ores have high moisture contents as well as chemically bonded water in the hydroxide form. Dehydration is a minimum and some pre-reduction of the ore in a rotary kiln is used to optimize the utilization of electric power for smelting operations in the electric arc furnace. Ferronickel production therefore typically uses a rotary kiln and electric furnace process. After the saprolitic ore has been sized for treatment and partially dried‚ it is fed together with a solid reductant to

Copper Sun‚ by Sharon Draper‚ is a telling of the story of a fifteen-year-old girl named Amari. It tells about her being taken from her home in Africa‚ being sold into slavery‚ her tales in the house she was sold to‚ and her escape. Many strong emotions are displayed‚especially through Amari‚ two that were very brightly displayed were fear and sadness. Fear is a distressing feeling or emotion‚ everyone will feel fear at one point‚ it’s caused by impending danger‚ evil‚ pain‚ etc. During the story

Extracting Iron from Iron Ore in a Blast Furnace The metal iron and its alloy steel is one of the most important substances used by man. Humans have been discovering the metal’s uses science 3500BC. Huge quantities are used in the construction industry to construct of all kinds of vehicles. The most common from of iron known is the oxide. The Iron is extracted from the ore that contains the most amount of iron. The iron is extracted from its oxide ore called Hematite. Many things are produced

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Determine the concentration of an unknown copper (II) sulfate solution by using colorimeter Introduction: The concentration of the solution also alterations the proximity of the solution. For example‚ the more focused concentration will frame to be denser than more weakened concentration of copper (ii) sulfate. This implies there is a connection between the concentration of an solution and its absorbance. Along these lines‚ this test is set up to discover the kind of connection between the concentration

Experiment 6 Title: Preparation of bis(acetylacetonato)copper(II) complex Objective: To synthesize the bis(acetyacetonato) copper(II) complex Theory/Background: All metal ions in solution are ’associated’ with water. The water molecules can also be weakly bonded or more strongly as a ligand to form a complex ion‚ and these can also present in solid ’hydrated’ salts of crystallization. E.g Copper(II) nitrate (Cu(NO3) 2.3H2O). A complex ion has a metal ion at its centre with a number
