The patio process is a process for extracting silver from ore. The process was invented by Bartolom233 de Medina in Pachuca, Mexico, in 1554. The patio process was the first process to use mercury amalgamation to recover silver from ore. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas.Chat Online

The role of drying in gypsum mineral processing. after gypsum ore is extracted from mines or quarries, it is crushed and stockpiled as needed. if the gypsum ores moisture content is greater than 0.5 weight percent, then the material requires drying. a gypsum dryer is commonly used to reduce the moisture content of the ore to the necessary level.
Preconditioning gypsum. gypsum ore is extracted from a quarry or mine and then crushed to a smaller, more manageable size. the materials moisture content is then assessed before entering a grinding mill. gypsum ore with greater than 0.5 weight percent moisture is processed using a rotary dryer. once the moisture content is at the ...

Silver processing, preparation of the ore for use in various products.. silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen.the lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3000 ...
Parting is the separation of silver from gold and a process during which the base metals are separated from both, but, as the presence of a high percentage of these base metals is injurious to the successful conduct of the processes which are chiefly in use, a preliminary refining by one of the methods already described is usually necessary.
After blasting, the ore is reduced in size with drop balls and loaded on the trucks with shovels for transport to the processing plant, where mica, quartz and feldspar are extracted. uses the principal use of ground mica is in gypsum wallboard joint compound, where it acts as a filler and extender, provides a smoother consistency, improves ...
