This video shows a Gold Concentrator for commercial gold mining. Designed for primary concentration of alluvial or milled hard rock ores, runs on either clean or turbid water. Excellent fine gold recovery. Available in three sizes. The mine site in this video is mostly glacial till. They replaced their jig system with the Centrifuge for better recovery of the fine gold. We also build a Secondary Concentrator, the "Martin" Multi Helix Gold Spiral. See our website at www.oro-industries.com or call 214-736-8554. Oro Industries -Yuba Goldfields, Marysville, Ca. USA.

Solartron Energy Systems Inc. has created the SolarBeam Concentrator is the word's first affordable parabolic solar concentrator for thermal hot water production. One system provides peak 10kw/hour (34000 BTU/hour) of hot water capable to heat a 2400 sq. ft (222 m2) house. The solar collector area of the SolarBeam Concentrator is 121 sq ft (11.3 m2) and concentrates the sun's heat on a 10"X10" (25X25 cm) heat exchanger. The SolarBeam has dual-axis sun tracking and is available for commercial, government, and residential applications. Payback is typically 6 years with government incentives. SolarBeam is 262% more efficient than solar flat plate hot water panels and 98% more efficient than evacuated tube panels. The system is also capable of generating 3.5 kW/hour of photovoltaic electricity as well provide air conditioning in conjunction with absorption chillers. SolarTron Energy Systems Inc. is currently looking for global distributors.

DigInfo - movie.diginfo.tv Previously, polish processing was the only way possible to manufacture compound parabolic concentrators (CPC). Isuzu Glass has announced that it has successfully produced CPCs using a glass mold process. This new process makes it possible to reduce CPC production costs. Applications cover the full range of LED products (projectors, lighting devices, et cetera) because it is possible to significantly increase light intensity. In addition, CPCs manufactured using this new production method can be used in solar power systems (concentrating photovoltaic systems) since they can transfer sunlight to solar cell elements efficiently.

One year ago, Solartron Energy Systems Inc. introduced the world to the first commercial available solar concentrator. The new 15ft (4.5m) diameter SolarBeam is capable of providing 13kW (44000 btu's) of thermal heat per hour. Unlike solar flat plate panels or evacuated tubes that lose efficiency with higher operating temperatures, the SolarBeam maintains a continuous 82% efficiency. Solartron Energy has a market reach as far as Western Africa to Australia in addition to our North American market. You will see an example of the SolarBeam providing heat for 3X 120 gallon tanks and a 1000 gallon tank for a national bottling plant.

PV / T co-generator. Using optical devices such as mirrors, fresnel lenses, etc., it is possible to collect solar light and concentrate its energy on a single small area solar cell (photovoltaic). This reduces the total cell area an amount equal to the concentration ratio and thus decreases the cost of the PV system, as a relatively inexpensive optical concentrator replaces the expensive semiconductor material. Moreover, using light concentration boosts the cell conversion efficiency. In addition - the water as an infrared filter prevented overheating of solar cell that increase it power output significantly. More see at www.tonchev.org

You can discard the large shaker tables, the GOLD REAPER is very mobile and processes feed size up to 3mm (about 1/8 of an inch). We ship across the world. One ounce of gold almost buys a REAPER. It is light and easy to carry and does not corrode.

Hi all! I present a simple method for gold separation. The project is open source! :) This is a prototype. I used the laws of nature! Put some sand into the container. The sand could be after panning, prospecting, sluice boxing, sniping etc. Create vortex, and there will be fast separation! After the deposition has rinsed, the excess material flows out of the container across the prepared holes. As a final step, use a pan for the perfect separation. In this video i couldn't use real gold for this presentation!!! Just some heavy minerals and magnetite, hematite, silver, chrome, etc. Now i make a big quantity version of the separator with 25 litres buckets!!! My goal is to develope a fast and simple method. Cheers! If you liked the video, then vote!

This demonstration shows the effectiveness of the cyclonic action of the F4 Cyclone Gold Concentrator. I also introduce Gold Saver, a solution to make the water wetter. It will penatrate your concentrates and allow the gold to drop out easily. In the video you will see a "foam" it is the bubbles of air that will suspend the find gold. These bubbles will attach themselves to the finer gold and you discharge the gold. Gold Saver breakes the surface tension and drops the gold to the bottom. The cyclonic action you see in this video is highly effective. At the end of the video you will see the gold that was recovered from the 30 mesh concentrates. Also notice the cyclonic action at the cone. This is unique to the F4 Cyclone Gold Concentrator just as a F4 tornado or Cyclone is to nature.

SolarBeam is installed at the municipal building in Amherst, Nova Scotia, Canada to provide solar hot water for the facilities heating system. When the sun is shining, the SolarBeam provides free solar hot water from morning to evening because it can track the sun throughout the day. There is no issue with snow collecting on the SolarBeam because when the system starts tracking the snow starts sliding off. The snow shown on the SolarBeam right now used to be almost a foot deep in the morning. The SolarBeam's parabolic dish has a black backing, so as the sun reflects on its surface, it gets heated and slides off. The system provides an average of 10kW of thermal heat per hour. The SolarBeam is sold through distributors around the world and can be used in any application that uses hot water. For example: fire stations, schools, hospitals, beverage companies, pharmaceutical companies, wineries, government buildings etc. The SolarBeam can be installed in the ground or on a concrete flat roof. The SolarBeam 's parabolic dish is 15 feet wide and the post is 8 feet tall. It uses anodized aluminum as its reflective material, not glass. This makes it very safe to use in residential and commercial applications. For more information about the SolarBeam, check out the website at: www.solartronenergy.com
