When zinc contacts copper in the presence of an electrolyte (such as water) a galvanic reaction will lead to corrosion of the zinc and subsequent failure of the roof or wall cladding. Run-off from a copper surface to a zinc surface must be avoided under all circumstances.

Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.
Lead/Zinc Separation Process and Circuit Flowsheet. Extensive batch and pilot plant testing and actual plant operating experience has established the above flowsheet as typical for the average zinc sulfide ore containing galena and usually pyrite in a lime or siliceous gangue.
From: Shuikoushan Lead Zinc Mine, Changning, Hengyang Pref., Hunan Province, China - Dimensions: 130x106mm - Sold by: Well-Arranged Molecules - Deep red complex crystals of Sphalerite sit on a plate of sparkling reddish quartz. Some are claiming the quartz is red due to inclusions of Sphalerite, I am not sure about that. There is galena here too and the back of the piece is crystalized calcite.
Gold and silver are obtained from a variety of ores, in some of which the gold predominates, in others silver is the primary value, while in still a third class these two metals may be mixed with the base metals, such as lead, copper, zinc, and iron.

Zinc is a very useful metal, and used to plate iron, and protect it from corrosion, in a process known as galvanization. Zinc also is used in many other alloys, such as brass and solder. An alloy of zinc and aluminum is nearly as strong as steel and as easy to mold as plastic.
A lead-zinc ore may also contain gold and silver, lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. Lead and zinc ores are mined primarily underground in countries including China, Australia, Canada, the Unites States, and Peru.

Native lead, a rare mineral, occurs in a late-stage vein in the world's largest lead – zinc – silver deposit, at Broken Hill, Australia. The lead-bearing vein consists mainly of laumontite, quartz, biotite and muscovite, together with minor amounts of lead, galena, sphalerite, molybdenite, and rare allanite-(Ce).

Lead and Zinc. Lead and zinc ores are found so often mixed that they are described together. In addition to galena and zinc blende, pyrite is generally present and often in considerable quantities, and copper pyrites is generally present. By weathering, the latter may leave green and blue stains. The ore deposits are of two principal kinds:
