Metals are extracted from their ores which contain several impurities, the lighter impurities are removed by slag formation.

What is the function of slag for welding?
The slag in the welding process protects the weld from oxidation and slows down the rate at which the weld cools. It also prevents brittleness of the metal.
Why is carbon used to extract metal from ores?
It's used as a reducing agent. The carbon (or specifically the Carbon Monoxide produced by the heat of the furnace) "grabs" the oxygen from the ore (an oxide) producing Carbon Dioxide and the metal. The combustion of the carbon also provides the heat required for the extraction. If the ore is not an oxide, another method of extraction needs to be used.
What is produced when reacting a metal with an acid?
What is produced when a acid reacts with a metal
What ethical issues are there with metal extraction?
The ethical issues with metal extraction is that it uses fossil fuels which which causes a large carbon footprint. It damages the ground around it and it causes pollution due to burning furnaces which can be a contribution to globel warming :)
What is the difference between isolation an extraction?
Isolation is the process of the seperation of the two metals but extraction is the process in which we get the desired metal from the concentrate.(in general we can say from the minerals and ores)
What is slag a rock?
A slag rock is an artificial rock. Slag is made as a byproduct of industrial processes such as metal mining. It is also produced by iron smelting such as in steel mills.
Which material formed during smelting is denser molted metal or slag?
The molten metal is the denser material, the slag floats on top of it and can be "scooped" off during the smelting process.
What is slag from welding?
Slag is the residue left on a weld bead from the flux. It shields the hot metal from atmospheric contaminants that may weaken the weld joint. Slag can also be globules of molten metal that are expelled from the joint and then re solidify on the metal surface. in either case, they are usually chipped away with a slag hammer.
What is a word for molten metal scum?
slag
How do you remove slag after smelting metal?
slag of induction furnace having 49% of feo . is it higher side
What is slag optimization?
Slag purifies and removes unwanted materials from metal. Optimization is the application of foams and other agents to enable a higher quality and stabilized slag to produce a higher quality metal product. Efforts are made to achieve an optimum slag viscosity by the fixation of basicity and temperature.
What are the solid wastes of metal extraction called?
it means when you exxtract metal from a mineral ore the solid waste left behind is rock because since you have concentrated the mineral in the mineral ore the mineral ore comes in liquid form and leavess behind rock
What is the four letter word for metal waste?
slag
What is an impurity found in the iron produced in the blast furnance?
Slag
What are the causes of slag inclusion?
Slag inclusions are nonmetallic solid material entrapped in weld metal or between weld metal and base metal. Slag inclusions are regions within the weld cross section or at the weld surface where the once-molten flux used to protect the molten metal is mechanically trapped within the solidified metal. This solidified slag represents a portion of the weld's cross-section where the metal is not fused to itself. This can result in a weakened condition which could impair the serviceability of the component. Inclusions may also appear at the weld surface. Like incomplete fusion, slag inclusions can occur between the weld and base metal or between individual weld passes. In fact, slag inclusions are often associated with incomplete fusion. Daniel
How can use the ore in useful way after extraction of platinum?
fill in the giant hole you dug with it and bind with the left over slag?
Is zinc produced?
Yes, zinc is produced by extraction from ores.
