Silver is a precious metal located throughout the world in geological deposits. Colorado's state nickname is the "Silver State" due to the large deposits of silver ore found there. Silver is extracted from the ore by a smelting or leaching procedure. Here's how to identify silver ore.
Mar 25, 2020· How Do You Identify Silver Ore? By Staff Writer Last Updated Mar 25, 2020 3:05:33 PM ET. Silver ore can be identified in the field by evaluating the physical properties of the suspected sample or by submerging it in water. It is also identified by examining the other minerals found around the suspected ore deposit.
Silver: Silver is generally found in serpentine, trap, sandstone, limestone, shale, or porphyry rocks, the gangue being quartz, calc, fluorite, or barite.All silver ores are heavy, and many of them are sectile, i.e., may be cut with the knife. Western men test for silver by heating the ore and dipping it into water.

Rich silver ore from the town of Tonopah in Nye county Nevada. Tonopah was one of the great epithermal silver and gold strikes of the early 20th century. The bonanza ore is rich in silver sulfides and also contains some free gold as well. Dark colored minerals of an almost sooty appearance are rich in silver.
Pyrite Better known as “fool’s gold,” pyrite was often mistaken by prospectors as gold because of it’s brassy color and shine. It’s name is derived from the Greek word pyr which means “fire.” When struck by iron, pyrite emits a spark of fire. Pyrite occurs in many different shapes and
Sep 05, 2019· Sulfide ore veins in rocks of all types are the typical home of this zinc mineral. Its iron content gives sphalerite a color range of yellow through red-brown to black. It may form chunky crystals or granular masses. Look for galena and pyrite with it. Luster: Adamantine to resinous; Hardness: 3.5-4
Nov 09, 2017· A picture would help a whole bunch. You can also identify mica via simple hardness test. Mica forms in lamellae; thin, flexible sheets so you can easily separate it at just the right spot with a fingernail, pick or small knife. It also crushes or breaks rather easily compared to the other minerals in the host rock.
May 10, 2018· Sources for ore rocks often exist in areas of stream flow in the form of placer deposits. In South America, pre-Columbian civilizations found platinum intermixed with gold in river deposits. The largest platinum deposits reside in Russia, South Africa and Zimbabwe, with smaller deposits in Canada and the United States.
identifying gold metal in the rock Many people who may have difficulty to identify the gold in the rock,because gold is usually often confused with the kind of carrier minerals pyrite,chalcopyrite,pyrhotite,pentlandit and gold -colored mica,because the mineral carrier is very similar to a vein of gold ore .

Silver ore can be identified in the field by evaluating the physical properties of the suspected sample or by submerging it in water. It is also identified by examining the other minerals found around the suspected ore deposit.
Most of the silver produced today is a byproduct of mining copper, lead, and zinc. The silver occurs within the ores of these metals in one of two ways: 1) substituting for one of the metal ions within the ore mineral's atomic structure; or, 2) occurring as an inclusion of native silver or a silver mineral within the ore
Apr 25, 2017· To the untrained eye, gold ore may look like rock with copper tones flowing within it. However, professional prospectors know how to recognize gold ore within a multitude of minerals. Recognizing the look and the location of gold ore is easier if you know how to find lode and placer deposits. General descriptions of

Apr 12, 2017· How to Identify Iron Ore. The earth's core is made up of iron ore. Early man made tools and weapons from the iron ore they extracted from the earth and refined. Only meteorites carry pure iron ore, and the deposits locked away within the Earth require mining and refining. Layered deep in organic deposits, iron ore
Oct 08, 2019· Green and greenish rocks get their color from minerals that contain iron or chromium and sometimes manganese. By studying a material's grain, color, and texture, you can easily identify the presence of one of the minerals below.Be sure to examine your sample on a clean surface and pay close attention to the material's luster and hardness.
Silver is a shiny grey even before being polished but develops a black film over time and has to be polished. Silvers melting point is 961.78°C (1763.2°F). Silver has the highest electrical conductivity (more electricity can pass through it) than any other metal. Silvers density is 10.49 g/cm^3. Silver is nonferrous.
Platinum is the rarest and most expensive of the popular precious metals. It is much rarer then Gold. Due to its rarity and value, it is not readily available to mineral collectors and is seldom represented in in all but the highest-end mineral collections.
If these two tests are not feasible then find the density of the object. This will identify Pt from silver-coloured base metals. To measure density: Find the mass of the object (in grams) and find its volume by the volume of water it displaces (in cubic centimetres). Divide the mass by the volume to obtain the density (grams/cubic centimetre).
Pyrite Better known as “fool’s gold,” pyrite was often mistaken by prospectors as gold because of it’s brassy color and shine. It’s name is derived from the Greek word pyr which means “fire.” When struck by iron, pyrite emits a spark of fire. Pyrite occurs in many different shapes and

Sep 06, 2019· To identify gold inside of a piece of quartz, hold a magnet against the rock. If the quartz sticks to the magnet, then it contains iron pyrite, or fool’s gold. You can also try to scratch a piece of glass or unglazed ceramic with the gold portion of the rock. Real gold will not scratch these substances.
Hematite is the highest grade iron ore and is often found as small nodules while hunting meteorites. While it may not always stick to a magnet many times it does. The red powder from Hematite has been used throughout human history as a color pigment.

Feb 05, 2020· The .925 stamp is reserved for sterling silver, and refers to the silver content, at 925/1000 or 92.5 percent silver. If it was marketed as platinum, chances are you got ripped off and were sold a silver ring, or the ring is silver and plated with another metal, such as rhodium or platinum.

magnetic field. It has a silver metallic luster and is a variety of the iron ore magnetite. These specimens were found in the United States. Malachite Malachite is a green copper carbonate mineral. It often displays swirled and banded patterns in shades of light through dark green. It is a very heavy material because of its high copper content
However, these rocks always have that red streak on them. When made into powder, the color of the powder is red, which is why it’s also called “haimatitē”, meaning blood-like. Like other crystals, it’s also believed to have healing powers. Those who practice alternative healing use this rock for healing broken bones, insomnia and stress.
The color of the mineral powder is not always the color of the mineral itself. By using either a streak plate, or an unglazed tile, you can find your specimen's streak color. I hope it helped you identify any rocks and minerals in your possession. Add Tip Ask Question Comment Download. Second Prize in the Explore Science Contest 2017. View
