VACUUM ASSISTED PAN FILTER MINERAL OR CHEMICAL PROCESSING PLANT
Refining plant with multiple purposes:
- Precious Metals
- Precious Gems
- And many others
The whole system is designed to handle small particles, introduce them to a lixiviant, classify and separate. The Pan Filter is vacuum actuated and draws the liquids away from the ore and cakes the residual. This plant was originally designed for the extraction of oil from oil sands so the entirety of the plant is Class 1 Div. 2
The Oil Extraction machine is 40’ tall and occupies approximately 3,800 square feet. This Machine uses a 16′ Vacuum assisted BOKELA pan filter aided with a series of Hydro-Cyclones to extract Oil from the Ore at a rate of approximately 100 tons per hour. This process could be adapted for many other uses such as Mineral extraction, Precious metals, Gypsum, etc. etc.
Oil sands are an unconventional oil resource where heavy; tar like oil is trapped in sand with a consistency similar to that of fresh blacktop. This resource is technically challenging to recover. In Sparks, Nevada a new technology has been developed to use solvents to cleanly remove the oil form the oil sands. This technology allows for greater removal efficiency of oil and eliminates the need for the massive water usage and generation of tailing ponds.
This oil extraction process consists of a mixer, Vacuum system, slurry pumps, sonic gauges and meters, air purification system, storage vessels, hydro-cyclones and a rotating pan filter. Oil sands will be first mixed with a class IIIB heavy solvent (chosen for its low flammability). Next, the ore solvent slurry mix will be pumped into hydro-cyclones, where the majority of the solvent will be separated from the Ore. The concentrated ore/solvent slurry flows down onto a 16 foot Vacuum assisted Bokela rotating pan filter, where the remaining solvent will be separated from the ore. The ore and solvent will then be transported into separate storage tanks. The discharged ore and solvent can then be recombined and recycled through the unit again for additional testing, minimizing waste generated by the process.
The Dynamic De-oxygenation unit is a repetitive process designed to extract Oxygen/hydrocarbons from material using Nitrogen injected through air knives in the down tube at a maximum flow rate of 70 SCFM or 4200SCFHr. The material travels on a series of conveyors (480V 10Hp motors with gear reduction) All data and activity is recorded and monitored through a series of Hazardous location sensors and cameras. The material drops through the down tube where a Feeder (interchangeable Gravimetric or Posimetric) controls the amount to continue on the repetitive process. The process continues until desired Oxygen/hydrocarbons level is reached. At which point Material is loaded into hoppers and transported to the extraction process. Oil Extraction process over view:
- Ore is deposited in De-Ox using forklift drum handler attachment through a 2 inch grizzly
- Ore is repetitively processed through a series of Nitrogen discharging knives in downtube until desired Oxygen levels are reached.
- Ore is dispelled into Forklift mounted hydraulic hopper and transported to the Oil extraction process machinery (SAPU-Lite)
- Ore is dumped into hopper at base of Belt conveyor and fed up to drum mixer.
- Solvent is then mixed with ore, then dumped down through Swecco screen into Flexicon screw conveyor system.
- Ore/solvent slurry is elevated up to Hydro-Cyclones where the majority of the solvent will be extracted.
- Ore/Solvent slurry will flow down to Bokela pan Filter (remaining solvent will be separated from ore)
- Cake/solvent/Product will be separated into separate storage tanks
- Cake to be dispelled
- Solvent to be reused
- Product to be stored in tanks on-site
