Sulpher Transmuted into Gold Dissolve common sulphur, or any vegetable carbon, in common salt. This solution will make the sulphur of a red colour. Keep this solution for at least one hours space in the fire, and a little of the sulphur will be found changed into gold. To the red salt adjoin the calx of Saturn.

Openpit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure Openpit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.

Gold, like iron, copper, lead and tin is a metal. Gold is the only yellow metal and is chemically very stable. It does not readily combine with other substances and, therefore, does not corrode or tarnish. Because of this property, it is almost always found in nature as pure gold. This is referred to as 'native gold'.

It is used for the purpose of an easy exhaustion of mercury. Prepare a brick, eight angulis square, with its surfaces made very smooth. Make a pit at the central part of this brick, by means of glass, and plaster the surface of the pit with lime. Then, prepare a cake of mercury, mixed with mica, silver, or gold, or with the essences of the same.

Alchemy (from Arabic: alkīmiyā; from Ancient Greek: χυμεία, khumeía) is an ancient branch of natural philosophy, a philosophical and protoscientific tradition that was historically practiced in China, India, the Muslim world, and Europe. In its Western form, alchemy is first attested in a number of pseudepigraphical texts written in GrecoRoman Egypt during the first few centuries AD.

The Coal Pits consists mostly of wide open passages composed of thick sections composed of coal vein and grey rock, with wooden beams blocking off certain areas or providing platforms to stand on. The long tunnels are frequently dead ends which necessitates lots of backtracking to progress further, unless digging or explosives are used.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

A number of different methods can be used to separate gold from its ore, but one of the more common methods is called gold cyanidation. In the process of gold cyanidation, the ore is crushed and then cyanide ((text{CN}^{})) solution is added so that the gold particles are chemically separated from the ore. In this stage of the process, gold ...
