Previously, making new reservations and checking the status of your delivery could only be done during business hours, but now it is possible anywhere, anytime.
In MEX, you can see photos of each lot after the arrival at the smelter. Also, you can check the status of your delivery in real time.
We have strengthened the protection of transaction information by complying with major standards such as ISO 27001, ISO 22301, and SSAE SOC 2 Type 2, which require transparency in the way personal information is collected and used.
By taking advantage of the Mitsubishi Process for continuous copper smelting, that has achieved the industry's top environmental impact reduction performance, we are expanding the acceptance and processing of E-Scrap, aiming to both promote recycling and address climate change.
Processing capacity of E-Scrap in fiscal 2019 was 160,000 tons, retaining the world's largest capacity.
With the knowledge and experience for the sampling and analysis accumulated over the years, we have been able to design and implement optimal processes.
We accept materials that contain gold, silver, copper, platinum, and palladium.
to see some examples of materials that we accept.
It will be either at the Naoshima Smelter & Refinery, Onahama Smelter & Refinery, or MM Metal Recycling (MMMR). In addition, Mitsubishi Materials has five collection yards in Japan (Kurihara City, Tokyo Port, Nagoya Port, Osaka South Port, and Fukuoka Kanda Port) for small-lot shipments from domestic suppliers to the Naoshima Smelter & Refinery. Transport vehicles and ships arranged by Mitsubishi Materials run regularly from the collection yards to the Naoshima Smelter & Refinery. Small-lot materials sent to the collection yard will be transported to the smelter. The destination may differ depending on the shapes and properties of the material.
Acceptable packings are: bulk, flexible container bag, cardboard + pallet, bale + pallet, drum + pallet.
Basically, we accept a minimum of 1 wmt per lot. However, depending on the material, we may be able to accept a lot size smaller than the above, or we may not be able to accept a lot size larger than the above.
Examples of materials that cannot be accepted are as follows:
- Items that pose a high risk to health and safety, and materials that may cause pollution.
e.g. batteries, products containing CN (cyanide), etc.
- Items that may affect the quality of our products (bullions, chemical products).
e.g. containing large amounts of heavy metals such as Pb and As
- Items that may have an adverse effect on our facilities.
e.g. generates heat (50°C or more), has a high chlorine concentration, etc.
The process is as follows.
1. Reservation and Shipment
- On the day of delivery, please bring in the materials with the prescribed documents (can be printed out from MEX).
2. Weighing
- Weigh the materials using a truck scale or a platform scale.
3. Inspection
- An inspector will visually check the weighed materials to confirm that they are acceptable.
- We also determine the appropriate sampling method according to its properties and shapes of the material.
4. Sampling
- Sampling is performed using a variety of methods according to the nature and shape of the raw material.
- In addition to the four types of auto-sampling systems, we have five types of manual sampling methods, and we select the most appropriate sampling method for each of the various types of scrap materials.
- The auto-sampling system is a fully automated process that covers the entire process from material loading to representative sample extraction, enabling objective sampling without the need for human intervention.
5. Sample Preparation
- The collected samples for assay are sent to the analysis laboratory, where they are prepared into analysis samples through moisture measurement, crushing, dividing, matte fusion, etc.
6. Analysis
- The prepared analysis samples are analyzed according to ISO standards.
7. Reporting of Analysis Results
- We report the analysis results through MEX.
8. Payment
- Payment is made based on the analysis results.
In order to ensure fair and impartial sampling, we use a variety of auto sampling system (please click here for an overview of each sampling system). If you register and login to MEX, you can check the actual sampling method of your materials delivered.
In addition to materials containing gold, silver, copper, platinum, and palladium, Mitsubishi Materials Group accepts tin and lead scrap materials, industrial waste, and other materials. For more information, please contact us.
