Revolutionizing sustainability with a plant-based gold leaching solution and technology to recover gold from ore while reducing environmental impact

VANCOUVER, British Columbia - Nov. 30, 2023 - PRLog -- Manipueira Gold Recovery Technology Inc., ("MGRT"), a development Company with preliminary schematics prototyping the world's first sustainable precious metals manipueira leaching center ("Manipueira Center") which is designed to use the abundantly available, low-cost extract solution from the cyanogenic bitter cassava plant, commonly known as manipueira or cassava wastewater, as a lixiviant. Manipueira  is proven to recover 2 - 3 times more gold from ore than by using mercury, a deadly neurotoxin, and gold faster and less costly in tailings wastes remediation than by using hard to handle cyanide salts.

Say goodbye to cyanide salts used in ASM tailings wastes remediation, in ASM and large-scale mining (LSM) leaching operations.

According to Nural Kuyucak and Ata Akcil 2013 publication; "the extraction processes of gold, silver, and various metals from ores consume 13% of 1.1 million metric tons of hydrogen cyanide produced worldwide annually."

Say hello to manipueira, nature's safer solution destined to impact the future use of mercury and cyanide salts in the global LSM and ASM mining sectors.

In 2021, global cassava production was estimated at 308 million tonnes with Africa's total production being about 203 million tonnes (about 56% of world production), followed by Asia (84 million tonnes) and America with 26 million tonnes.

30 – 35% of the plants weight is the manipueira solution which is produced when the plant is crushed by flour manufacturers who recklessly discard it to the environment. It stinks when fermented, attracts insects, creates human health threats, causes biodiversity destruction, contaminates the soil and drinking water, and pollutes the rivers. Discarded cassava wastewater represents a global loss of an estimated 92 million tonnes of cyanide annually.

"The symbiosis of artisanal ore processors and flour makers is a win-win situation to reduce mercury environmental pollution while mitigating an unintended consequence of harvesting the bitter cassava plant."
