If it is desired to estimate the whole amount of gold and metallic silver amalgamable in the ore, a similar experiment may be made by weighing up 250 grams of the pulp, diluting with water at 1:1, and agitating violently with mercury for about 30 minutes. The mercury is then panned from the pulp, and the latter assayed.
Gold. Gold is the third element in the eleventh column of the periodic table. It is classified as a transition metal. Gold atoms have 79 electrons and 79 protons with 118 neutrons in the most abundant isotope. Under standard conditions gold is a shiny yellow metal. It is very dense and heavy, but also fairly soft.
2、Ore Dressing Technology and Equipment. The selection of sand and gold mine is mainly based on the physical properties of minerals, such as grain size, shape and specific gravity, so as to achieve the purpose of sorting in the moving medium flow. This is the oldest method of selection in Mineral Engineering--Gravity concentration method.

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
