Germanium Stone Recycling

Germanium ore refers to an ore containing germanium, a metallic element with the chemical symbol Ge. Germanium is usually present in small amounts in some ores rather than as a separate mineral. The main ores of germanium include sphalerite, galena, and galena. Germanium is a semiconductor material with important applications in electronics and optoelectronics. It is used in the semiconductor industry to manufacture solar cells, optical fibers, and other electronic devices. The mining and extraction of germanium ores are essential to meet these industrial needs. However, the output of germanium is relatively small, and it is mainly extracted as a by-product from the smelting process of metals such as zinc and copper. It should be noted that although germanium exists in some ores, its content is usually low, so the extraction of germanium usually requires a specialized smelting and extraction process.

Steps for recycling waste germanium ore:

1. Ore beneficiation: Selecting ores with higher germanium content through physical and chemical methods. This stage aims to improve the efficiency of the subsequent extraction process and ensure that the selected ore is more likely to contain economically viable germanium content. Physical methods may include techniques such as gravity separation, while chemical methods can determine the presence and content of germanium by dissolving the ore.

2. Ore crushing: The selected ore is mechanically crushed, a process designed to break the ore into smaller particles, making subsequent processing more convenient. Mechanical crushing can use equipment such as crushers and jaw crushers to ensure that the particle size of the ore is suitable for subsequent leaching and extraction processes. The crushed ore is more likely to react with chemical solvents, which helps to effectively dissolve and extract germanium.

3. Ore leaching: The mechanically crushed ore enters the ore leaching stage, where the ore is exposed to a chemical leaching solution, usually using an acid solution or other solvent to dissolve the germanium. This process is a key step in separating germanium from the ore, by dissolving the germanium and allowing it to enter the solution to form a chemical complex containing germanium.

4. Solution extraction: The ore solution is extracted by chemical methods to effectively separate the germanium from the solution. This process usually involves the use of organic solvents or other specific extractants that can selectively form complexes with germanium to achieve effective extraction of germanium.

5. Separation and purification of germanium: The germanium extracted from the ore solution is separated and purified to remove possible impurities. This stage involves the use of different chemical and physical means to improve the purity of the germanium. Possible steps include extraction, dissolution, filtration and other operations to ensure that the final germanium product has the required high purity to meet the requirements of industrial applications.

6. Precipitation or crystallization of germanium: The germanium separated and purified from the ore solution is further treated to precipitate or crystallize by controlling the conditions of the solution. Through this step, the purity of the germanium is further improved and impurities are removed more thoroughly. This may involve adjusting operating conditions such as temperature, concentration, pH value, etc. to promote the precipitation or crystallization of germanium.

7. Smelting: The germanium is separated from the solid state in liquid form to obtain the final germanium product. The smelting process usually involves high temperature conditions, and the treated germanium material is placed in a furnace for heating to melt it and obtain pure germanium liquid. The process also helps to remove other impurities that may remain in the germanium, ensuring that the final product reaches the required high purity to meet the requirements of semiconductors, solar cells and other high-tech applications.
