Example 3: Determine the charge on a piece of copper if you rub it with a piece of silk. Looking at the electrostatic series, copper is closer to the top with silk beneath it. This means that the copper is negative and the silk is positive. Charging by Conduction Conduction just means that the two objects will come into actual physical contact with each other (this is why it is sometimes called

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised ...

When an electric current is passed, the electrolyte solution breaks into Cu2+ ions and SO42- ions. The Cu2+ move towards the negative electrode i.e iron key here and is deposited on it forming a thin layer of copper on it. SO42- ions move towards the anode releasing electrons there to flow through the circuit.

A data flow diagram (DFD) maps out the flow of information for any process or system. It uses defined symbols like rectangles, circles and arrows, plus short text labels, to show data inputs, outputs, storage points and the routes between each destination. Data flowcharts can range from simple, even hand-drawn process overviews, to in-depth ...

2. Use the Passive Tense. The diagram gives you several of the verbs that you need to describe each stage e.g. drying, soaking, polishing, flattening. Again, you have the problem of avoiding using these words exactly as they are in the text.. So using the Passive Tense gives you an easy solution.. Even better, when describing a process you only use the Present Simple Passive.

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
