This 13%is the maximum value. If the maximum value is the human intentional loss, it is also called leakage. Natural loss within 13%. But this natural loss is not to say that as long as there is processing, there will be 13%of the loss. It gold returns to processing more or less, but some are artificial, some are natural, and natural loss is very small, and it is generally not visible. Remember not to frequently return processing. There is no loss, but the number of times is too much. The expansion information: silver, a type of transition metal. Chemical symbol AG. Silver was one of the metals known and used in ancient times, and was an important precious metal. Silver has a single quality in nature, but most of them exist in silver ore in the form of compliance. The nature of silver is relatively stable, with good thermal conductivity and electrical conductivity, soft and extensible. Its reflective rate is extremely high, up to 99%. There are many important purposes. gold is chemical element, chemical symbol AU, atomic order 79. Pure gold is a metal with bright luster, red, soft, density, high density, and ductility. It is one of the rare, precious and extremely valued metals. At the same time, it is also an important material for the jewelry, electronics industry, modern communication, aerospace and air industry and other departments.
