For a straight answer, the melting point of gold is 1,948 degrees Fahrenheit or 1,064 degrees Celsius. That's hot enough to burn through car engines, the Earth's crust, and many other metals. But how …
The melting point of gold is 1064ºC, so your blowtorch is inadequate. You have to melt the gold in something, and the borax acts to cover it, allowing the dense gold to settle, dissolving various metal oxides that might contaminate your flakes, and floating above the gold.
In this process, hot metal or gold, in this case, is poured in a molten state into the mold. Post-this, the pressure in the mold is lessened to approximately 2.0 atmospheres or so. Does melting the gold purify it? …

For this experiment I chose 2 types of common plumbing solder, 50/50 blend of tin/lead and silver solder, having a melting point of 180-190 °C (360-370 °F) and 450 °C (840 °F) respectively. There's other metals that could be smelted this way, like zinc (and plutonium?).
The granules were almost certainly formed by melting gold in a pot of charcoal (not as has been also suggested by dripping molten gold on to a marble slab) and to adhere them to a gold surface is by no means an insoluble problem, but one which most students of goldsmithing learn to solve at art school.
The process is carried out at temperatures between 800 and 900°C, i.e. lower than the melting point of the noble metals, and even below the temperature at which the slag becomes totally molten.

The melting temperature of Gold is 1064.18 °C. According to wikipedia flame temperatures as: Wood 1027 °C, Charcoal fire 750–1,200 °C So it doesn't seem unreasonable that a pot on a coal fire could melt a …
1 Wash, filter and grind the granite ore with into smaller pieces. 2 Put the ground ore into a tank containing a dilute cyanide solution and add zinc. The chemical reaction between a dilute cyanide solution and zinc will separate the gold from the ore. 3 Use a filter press to remove the gold from the solution.
use the valves on the torch. turn on the fuel and light the torch. open the oxygen enough to turn the flame blue. adjust the flame to where the blue flame is very gentle with very little noise. it doesnt take extreme heat from a torch to melt gold. there should be two parts of the flame. a light blue flame that big and long and then theres a …
In point of fact, the purification of gold using fire's earliest form is melting. However, the temperature at which gold melts is 1064 degrees centigrade or 1947.2 Fahrenheit and melting it at this point poses a …
Once you find gold in quartz ore, you can extract gold by the flowing steps: 1 Use a sledgehammer to break the rock into smaller pieces. 2 Place a steel anvil in a large pan to prevent the loss of the gold contained in the quartz stone. 3 Look for large pieces of gold that can be collected manually or with tweezers.

Melting is the procedure of altering gold from solid to liquid condition. This can be scrap gold for example jewellery, coins or fittings. However, smelting is really a chemical reaction that reduces metal oxides (gold ore) to pure gold as well as an oxide waste (slug). That's, technology-not only to acquire pure gold.
