The washed ore was then dried and formed into bricks. Next, the bricks of washed ore were heated in a furnace where the lead/silver mixture was released from it's sulphide and separated from iron oxide impurities and run-off into "pigs" or blocks. The pigs of lead were now placed in a high temperature (950 degC) 'Cupellation' furnace.

The central idea being that since gold is so heavy, if you execute the maneuver with some skill and experience, any gold that was there will be the last thing left. Look up 'gold panning' on Wikipedia if this wasn't clear. Now that you know what gold panning is, I think you be able to answer all of the questions you presented.
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.

When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold .
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
A similar case was noticed by Mactear in South America, where a limonite ore which only yielded from 35 to 40 per cent, of its gold when treated in Huntington pans, was made to yield between 85 and 90 per cent, by merely subjecting it to a dehydrating calcination before amalgamating it.
Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.
