Abstract
A method and systems are provided for extracting heavy metal from glass waste. Glass is initially crushed to a diameter size between about 10 nanometers and about 2 millimeters. The glass is then added to a tank having a solution of water and acid, where the acid removes metal from the surface of the glass particles. In some embodiments, the solution and glass particles are elevated to a configurable temperature above ambient temperature and circulated for a configurable period of time. The solution is then separated from the glass particles. In some embodiments, the glass particles are then rinsed while in transit to a final destination or in a separate rinsing tank.

A method to extract heavy metals from glass waste, comprising:
- crushing glass waste into glass particles;
- filtering the glass particles that are between 10 nanometers and 2 millimeters in diameter size producing filtered glass particles;
- filling a tank with the filtered glass particles, wherein the tank includes a solution of water (H2O) and Nitric acid (HNO3) producing a slurry;
- circulating the slurry thereby extracting heavy metals from the filtered glass particles and mixing the heavy metals with the solution producing treated glass particles and an acid solution that includes the extracted heavy metals and the solution;
- and
- removing the treated glass particles and the acid solution from the tank.
A method to extract heavy metals from glass waste, comprising:
- crushing glass waste to glass particles having a diameter sizes between 10 nanometers and 2 millimeters;
- creating a slurry that includes the glass particles and an acid solution;
- circulating the slurry for a period of time, wherein the period of time is determined based on a temperature of the slurry, and wherein during circulation heavy metals are extracted from the glass particles producing treated glass particles and the extracted heavy metals are mixed with the acid solution producing an acid mixture;
- and
- separating the treated glass particles and the acid mixture from the slurry.
A method to extract heavy metals from glass waste, comprising:
- crushing glass waste to produce glass particles having diameter sizes of 10 nanometers;
- transporting the glass particles to a treatment tank having an acid solution;
- regulating a temperature of the glass particles and the acid solution in the treatment tank;
- and
- circulating the glass particles and the acid solution within the treatment tank for a period of time based on the temperature producing treated glass particles with heavy metals extracted from the treated glass particles and the heavy metals mixed with the acid solution producing an acid solution.
