Simple method for extracting gold from electrical

Hello friends

Normally, gold extraction usually has chemicals left over from gold extraction, which is usually water, which will contain gold.

Today, I have a technique for separating gold from chemicals left over from gold extraction. We will use electricity to extract gold from the remaining chemical water.

You should make the chemical basic first, the pH should be at or near 7.

We will use electricity to pull the metals in the water to stick to the plate.

When we have the metal that is stuck to the plate, use nitric acid to dissolve the metal. There will be a small amount of gold and metals that nitric acid cannot dissolve. At this stage, we may need to extract

 the remaining gold with aqua Regia again to make it more pure.

Extracting gold using electricity is typically done through a process called **electrowinning** or **electrorefining**. Here are two common methods:  

### 1. **Electrowinning (Electroextraction)**  

- Used in gold mining operations to extract gold from a cyanide or acid leach solution.  

- Gold ions in solution are plated onto a cathode (usually made of stainless steel or carbon) using an electric current.  

- The process is efficient and commonly used in gold recovery from low-grade ores.  

### 2. **Electrorefining**  

- Used to purify gold after initial extraction.  

- The impure gold is made the **anode**, and a pure gold sheet is the **cathode** in an electrolyte solution.  

- When electricity is applied, pure gold ions move to the cathode, while impurities settle as anode sludge.  

These methods require electricity, chemicals, and careful control to ensure efficiency and safety.
