Professional gold mining in the 21st century is a large scale, modern industry, using advanced, clean and safe technologies. This is the story of how one of the world's most important metals is produced.
in Flexicone concentrators the liquefaction of the mineral bed in the grooves occurs due to the compression of the flexible cone from the outside by three rollers, which causes the particles in the grooves to approach and move away from the axis of rotation by 3-4 mm during one revolution of the cone 3 times. At the same time, a varying centrifugal force from 0 to 200 G acts on each particle. In addition, in our latest development, an easily installed magnetic system for removing the magnetic fraction also makes it possible to enhance the process of thinning the mineral bed due to the presence of a magnetic fraction in the pulp.
There were different techniques for different kinds of golds. On the one hand they were mining for nuggets in quartz veins, thats where you often see the old mining shafts. Other techniques used sluices made from different materials where they would use water to wash away the light sand and only the heavy gold concentrate is kept in the riffles of the sluices. The material would be normally taken from river beads from rivers which carry the gold that is getting washed out of the quartz veins. I am not an expert so take it with a grain of salt, but those are the general techniques I know of.
Most likely it's recycled or destroyed. Luckily it would be pretty easy to tell if they were just flushing it down the toilet. You'd have a lot of dead rats all of a sudden.
it's likely removed in the further refinement process, Gold is pretty commonly found in what are known as "complex ores" where you can find more then one valuable mineral, so the "waste" would be shipped off to a different facility with the equipment to extract other valuable minerals.
Really interesting....how you avoid talking about how gold replaces tropical rainforest in Papua New Guinea, Africa and the Amazon and the ecocide it causes, often resulting in the murder of Indigenous people.
@@PROVOCATEURSK Even if we ignore the fact that marching cattle across barren wastelands can restore entire eco-systems in a healthy way, how exactly would you advise the robbed and raped for centuries african people to sustain themselves? Where are all the forests our farmers destroyed for farmland? How many species have gone extinct because they ate crops, how many beautiful landscapes are now flat surfaces of wheat far and wide? Why don't you complain about that? Oh right, because it's how we feed ourselves. Whereas destroying landscapes for shiny stuff you can't eat or do much with should actually make you angry. Oddly it doesn't, how come?
Gold is the perfect currency. It's rare, easy to recognize, non-toxic and doesn't degrade. Or do you want to go back to a time where we use cows and sheep as currency?
