Blyläckor
Blyläckor, also known as lead smelting slags, are by-products of the lead smelting process. They are primarily composed of lead oxides, silica, and other impurities. The smelting process involves heating lead ore to high temperatures, which separates the lead from other elements. The resulting slag is a molten by-product that is then cooled and solidified. Blyläckor are typically gray or black in color and have a glassy or crystalline texture. They are often used as a construction material due to their high density and durability. However, they can also pose environmental risks if not properly managed, as they can contain hazardous substances such as lead and arsenic. Proper disposal and recycling of blyläckor are essential to minimize their environmental impact.
