Today you mainly use flotation for copper ores as these are normally low grade ores with fine grain dessiminated copper in it.
You basically put your grinded ore in an oil basin and let the copper stick to air bubbles you pump through it.
"The principal lead ore, galena, is properly known as lead sulfide, and sulfur makes up a substantial portion of the mineral. The flotation process collects the sulfur-bearing portions of the ore, which also contains the valuable metal. First, the finely crushed ore is diluted with water and then poured into a tank called a flotation cell. The ground ore and water mixture is called slurry. One percent pine oil or a similar chemical is then added to the slurry in the tank. The tank then agitates, shaking the mixture violently. The pine oil attracts the sulfide particles. Then air is bubbled through the mixture. This causes the sulfide particles to form an oily froth at the top of the tank. The waste rock, which is called gangue, sinks to the bottom. The flotation process is controlled by means of X-ray analyzers. A flotation monitor in the control room can check the metal content of the slurry using the X-ray analysis. Then, with the aid of a computer, the monitor may adjust the proportion of the chemical additive to optimize recovery of the metal. Other chemicals are also added to the flotation cell to help concentrate the minerals. Alum and lime aggregate the metal, or make the particles larger. Xanthate is also added to the slurry, in order to help the metal particles float to the surface. At the end of the flotation process, the lead has been separated from the rock, and other minerals too, such as zinc and copper, have been separated out."
This is how the lead is separated from the other materials found with it.
its seperated by the way tht its a coumpoun d and its not a mixture, its more of a solid and it can be easily removed so that makes the element, chromium have the chance to pe seperated or attached to another element, wheather its a solid or a gas.
Sulphur dissolves in carbon disulphide; cobalt does not. Make a slurry of the mixture in carbon disulphide, filter it to retrieve the cobalt. Now evaporate the filtrate to retrieve the sulphur.
how is cobalt seperated from other elements found with it
how is zinc sperated with materials found with it
yes. because zinc is most common element to be found in nature
Zinc is usually combined with other elements.
nitrogen aluminum and zinc are elements therefore they cannot be separated into several elements
Yes and it also can be made up of other materials
Zinc is a mineral, found in solid form.
I don't have a clue.

Zinc was found in Joemama in Asia

Zinc is an element. There is nothing but zinc in zinc so nothing can be extracted from it. Zinc can be combined with other elements to make useful products. It is used in rustproofing (galvanizing) and in skin ointments (zinc oxide). Avery tiny amount of zinc is necessary in human diet.
Zinc is a mineral, found in solid form.
Copper and Zinc, separated by a electrolyte.
Most zinc is recovered from zinc sulphide ore that also contains sulphide of other metals as well as silicon dioxide and perhaps other materials. Physical methods are used first to eliminate some of the undesirable substances then the ZnS is heated to recover the zinc. For more details please see the wikipedia article for zinc.
Zinc is found with copper and is also found with gold and nickel.
