Dang! Y’all think you can help me find my wedding ring? We’ll just throw my whole house in there and eventually the ring’s bound to turn up. It’ll be worth it, you don’t know my wife 😰😰😰
Up here in Ontario Canada, slag is only allowed in granular products. The chemical composition is too risky and may not be compatible with the bitumen in asphalt or cement in concrete. We have plenty of natural aggregate sources anyway. Some of the quarries have fantastic physical and chemical properties. A loose term “armour stone” is used when you get that stuff.

Not so, once you realize "slag" is mostly (but not exclusively) non-ferrous impurities like silicates, calcium, various minerals, other trace metals, etc. Smelting tech and rapid inexpensive mass spectrometry have advanced enough in recent decades to make recycling profitable as well as environmentally desireable, esp if you consider that there is often more metal present in old slag than there are in various lower grades of ore.
@@gregorymalchuk272 AFAIK it depends. Processing into aggregate for use in concrete or as RCS is probably a simple matter of iterative crushing and sieving to the desired size, whereas recycling for re-smelting is likely much more technically involved - what type of processing is done for the latter depends on lots of factors, including the type and quality of ore/material it came from, the type of smelter that produced it, the types and amounts of impurities present (i.e., phos and/or sulphur, et ), what product was being produced at the time (ex: a blast furnace processing first run ore into pig iron produces different slag than say an Electric Arc Furnace smelting a high alloy from raw materials that were already highly pre-refined and/or recycled). The local demamd/market plays a role as well I imagine. This is all armchair theory for me. Analogy: If life hands you lemons, whether or not you make lemon oil extract, dried lemon zest, lemon juice, lemonade, preserved lemons, food grade citric acid, animal feed, or some subset of all of the above products, depends on a lot of factors ... factors that vary from plant to plant, market to market, and company to company..
