I used them for our dental office scrap metal. I called and the sent collection jar and emailed me a shipping label. Once I sent it in, they had a system set up to make an account and I was able to follow along on the portal. I had used a middle man in the past and although I am not an expert in the precious metals, the amount of scrap was roughly the same as before but I got about 4x what I was paid last time. I will be saving up more scrap and using them again in the future.

We have a small jewelry shop in Michigan. Prior to starting our relationship with Core Scientific we did not have a refiner that dealt with gold-filled/gold plated items. Very happy to have the ability to give our customers something for GF jewelry items now. They also do a great job with sweeps and things.

My interaction with these great people was fantastic. They helped and walked me through the entire process. Explained every step, and what to expect. They made the whole process so simple. Very, VERY good people. No high pressure. Very transparent, explained every little detail. Even contacted me person to help. I highly recommend CORE Scientific. Thank you "all "at Core Scientific for ALL you did for me. Quality people and organization. I am 100% satisfied and happy. I wish you all the bestWell, my first review above was 100% right on. 100%!! Really. I have recently used their services again. And again, they were awesome. I cannot stress that enough. They helped every step of the way. I forgot to mention previously that they send you a report of exactly what metals are present, the amount, and the breakdown of what each metal price is worth. They are honest, helpful, and just plain old "Good People". So much so it feels like you are dealing with family. That is kind of rare in the world today. Thank you ALL at Core Scientific. Your kindness and professionalism are recognized and very much appreciated. I hope to deal with you again. Let me know if you ever come out my way again. Thank you again!

I’ve had an excellent experience working with Core Scientific for dental scrap refining. As a dental professional, it’s crucial to partner with a company that values transparency, accuracy, and professionalism—and Core Scientific truly delivers. Their process was clear and efficient, and I received a detailed report of the recovered precious metals from my scrap. The payout was fast and fair, based on current market rates. Their customer service team was responsive and knowledgeable, which made the entire experience seamless. I highly recommend Core Scientific to any dental practice looking for a reliable and trustworthy refining partner

We used to send our scrap into one of the big vendors for credit on our account and were getting around $500.00 for a full jar. We heard about Core-Scientific and decided to give it a go. Fast, friendly and financially beneficial. We received more than double what we normally had gotten in the past.

I think Core Scientific is a fantastic refining company. I've tried a few dental scrap buyers over my career, but Core Scientific pays me the highest value. They do not arbitrarily assign the gold to type A or B through visual inspection. I feel their technique gives the truest value and the highest payments to me.

Mike said that he could get me a better return, like everyone else, but I decided to give them a try. I am glad that I did. On my first two batches I received 2 to 3 times what I had been getting with my old refiner. I do recommend giving them a try.
