Question

Какими методами выпловляли серебро из руды ?

Answer 1

Цианирование (как сказано выше) - процесс, в котором на добываемый метал (в данном случае серебро) воздействует кислород с цианидом.

Амальгамация - это второй способ добычи серебра, в котором на серебро воздействуют ртутью. При контакте элементов образуется их влажное состояние, которое нуждается в избавлении от воды.

Answer 2

Цианирование (один из распространенных способов

Methods for Extracting Silver from Ore

Silver is commonly extracted from ore through various methods. Here are some of the methods that have been used historically:

1. Amalgamation: Amalgamation is a method that involves using mercury to extract silver from ore. The silver ore is crushed and mixed with mercury, forming an amalgam. The amalgam is then heated, causing the mercury to evaporate and leaving behind the silver. This method was widely used in the past but is less common today due to environmental concerns associated with mercury usage.

2. Cyanidation: Cyanidation is a process that involves using a cyanide solution to extract silver from ore. The ore is crushed and then treated with a dilute cyanide solution, which forms a soluble silver cyanide complex. The silver is then precipitated from the solution by adding a reducing agent, such as zinc or aluminum. Cyanidation is commonly used in large-scale silver mining operations.

3. Smelting: Smelting is a method that involves heating the ore to a high temperature to extract the silver. The ore is mixed with fluxes, such as limestone or silica, which help remove impurities. The mixture is then heated in a furnace, causing the silver to melt and separate from the other components of the ore. The molten silver is then cast into bars or other forms for further processing.

4. Electrolysis: Electrolysis is a process that involves passing an electric current through a solution containing silver ions. The silver ions are reduced at the cathode, forming metallic silver. This method is often used to refine silver rather than extract it from ore. However, it can also be used to extract silver from certain types of ore, such as silver sulfide ores.

It's important to note that the specific method used to extract silver from ore can vary depending on factors such as the type of ore, its composition, and the desired purity of the extracted silver. Different mining operations may employ different methods based on their specific requirements and available resources.
