At Hartza Refining, we offer a range of services to meet the specific needs of our clients. Our services include mobile refining, smelting, and assaying of precious metals, as well as gemological testing and diamond grading services. One of our unique services is the inspection of seller's goods for buyers who are not on the ground. We understand that it can be challenging for buyers to verify the quality and quantity of precious metals, especially when they are not able to visit the seller's location in person. That's why we offer an inspection service to provide our clients with peace of mind when purchasing precious metals remotely. Our team of experts can visit the seller's location and conduct a thorough inspection of the goods, ensuring that they meet the buyer's specifications. We also offer a mobile refining unit that can be transported to our clients' location for efficient processing of their assets. This eliminates the need for our clients to transport their precious metals, which can be costly and risky. Our team of experts will work closely with our clients to ensure that their assets are processed efficiently and accurately. At Hartza Refining, we are committed to ethical and sustainable business practices. We work closely with our partners and suppliers to ensure that our services are responsibly sourced and have a positive impact on the environment and local communities.
