The process is attributed to a mining specialist – Bartolomé de Medina who was the first to use a silver amalgamation with mercury to extract silver. De Medina' s technique involved mixing the ore with mercury and strong brine. This formed a mercury silver amalgam from which semi-pure silver could be obtained by distilling off the mercury.

This volume focuses on Latin America, since it was mainly there that Europeans (or their colonial descendants) actually engaged in mining in the 16th-19th centuries; elsewhere they traded metals mined by others. The principal metals produced, and in prodigious quantities, were silver, in the Spanish colonies, and gold, mainly in …

He first focused his attention on learning about new smelting methods from smelters in Spain but ...

The patio process is a process for extracting silver from ore. It is processed for separating silver from the ore by amalgamating it with mercury on an open floor. The process was invented by Bartolomé de Medina in Pachuca, Mexico, in 1554. The patio process was the first process to use mercury amalgamation to recover silver from ore.

Patio process: Low grade ore was crushed and ground into powder (through animal and human power), a mercury-silver mixture was created in which silver is chemically bound to mercury (the grey circles depicted in the painting), the rock and dirt particles were washed away and the evaporation of the mercury left the silver …

In 2020, 784.4 million ounces of silver were mined across the world according to Metals Focus. While production is forecasted to increase by ~8% to reach 848.5 million ounces in 2021, it's still greatly outpaced by growing demand for silver.

The patio process is a process for extracting silver from ore. Smelting, or refining, was necessary because silver does not occur by itself in a natural state like some metals. Instead, it is made up of a larger ore body. Thus, smelting, or refining, is necessary to remove other byproducts to get at pure silver.

Between 1571 and 1575, when the fusion process was introduced in the Andes, Peruvian silver production increased fivefold. In 1572, Viceroy Francisco Toledo organized the Mita, the conscription system of India, to provide enough labor to meet the expansion of silver mining into low-grade ores.

Silver (Ag), like gold, crystallizes in the face-centred cubic system. It melts when heated to 962° C (1,764° F). With a density of 10.49 grams per cubic centimeter, it is the lightest of the precious metals. It is also the least noble of the precious metals, reacting readily with many common reagents such as nitric acid and sulfuric acid.
