So, what are the metals that are alloyed with gold? Gold will form alloys with most metals, but for jewelry, the most common alloying metals are silver, copper, and zinc.

Copper Concentrates Cargo Handbook the world''s largest

The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24% up to 36% of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 89%.

Lead Essential Chemical Industry

lead and zinc are almost immiscible just above their melting points silver is much more soluble in zinc than in lead silver/zinc alloys have higher melting points than pure zinc. At 863 K zinc is removed by transferring the lead to a ''dezincing kettle''. At this stage the desilvered lead contains about 0.6% zinc and 0.0004% silver.

Brasses Official Site of Copper Development Association

Brasses are copper zinc alloys. In general, they have good strength and corrosion resistance, although their structure and properties are a function of zinc content. Alloys containing up to approximately 35% zinc are single phase alloys, consisting of a solid solution of zinc and alpha copper.

We produce copper, lead, nickel and zinc concentrates. The biggest source of raw materials for our smelters is metal concentrates. We also use certain intermediate forms and secondary materials. We purchase some of the raw materials from mines with which we have agreements.

Copper smelter Boliden

The value of the free copper, gold and silver in a copper concentrates for a copper smelter is depending on the recovery rate, LME copper price and LMBA gold and silver price. In this example the recovery rate for a copper smelter is 98.0%. The value of free gold and silver is normally greater than the value of the free metal for copper.

Zinc Wikipedia

Sphalerite, which is a form of zinc sulfide, is the most heavily mined zinccontaining ore because its concentrate contains 60–62% zinc. Other source minerals for zinc include smithsonite (zinc carbonate), hemimorphite (zinc silie), wurtzite (another zinc sulfide), and sometimes hydrozincite (basic zinc
