In the parting method, the ore is dissolved in a bath of hot concentrated sulfuric or nitric acid. Gold is recovered from the residue, and the clear solution is treated with ferrous sulfate to precipitate the silver.

It is not possible; filtration as a separating method is based on the difference between boiling points.
Both "used method" and "method used" can be correct, but they serve different purposes. "Used method" often acts as an adjective phrase to describe a method that has been utilized, while "method used" emphasizes the method itself, highlighting its application. Depending on the context of your sentence, you can choose either. Generally, "method used" is more common in formal writing.
method used to demonstrate an experiment or to imitate a phenomenon

the answer is extraction. represent
Mercury was used in gold mining because it could bind to gold particles, forming an amalgam that allowed for easier extraction of gold from ore. However, this method resulted in significant environmental pollution due to the release of mercury into waterways and ecosystems.
Panning was a method for separating gold from gold-bearing soil. It involved the use of a solid pan. An amount of potentially gold-bearing dirt was placed in the pan with some water, and gently swished and shaken around, a process which would bring the smaller particles of gold to the surface.
An insoluble solid can be separated by filtration from the liquid.
Examples: decantation, sieving, magnetic separation.
Gold is obtained from mines where it is found in rock formations or extracted from river sediments through mining activities. Major gold-producing countries include China, Australia, Russia, United States, and Canada. The process of extracting gold involves crushing the ore, separating gold from the other elements, and refining it into a useable form.

Check it out yourself freak. I'm joking. It Gravity separating.
The method used for separating substances dissolved in the same liquid is called fractional crystallization. This technique involves slowly cooling the solution so that different substances crystallize out at different temperatures, allowing them to be separated based on their solubility.
Gold phone numbers are for separating pay as you go numbers and pay by contract numbers. Gold phone number are customizable and personal to you and your business.
Separation funnel is used to separate a nonhomogeneous mixture of liquids.Titration is method of analytical chemistry.
They used pan,filters,and chisels. The pan was for putting the gold in, the filter was for separating sand and rocks, and the chisels were for breaking rocks
