Here is another idea. Ever since you people were framing me for some kind of digging gold.

And the relays were flooded with gold panning, gold mining.

So the idea is this:

 

Imagine this drawing is the backside of a truck. A giant container full of water. Almost up to the top.

The orange portion is where dirt (top left) (including the flakes of gold) would be dumped at the top.

The first layer of panel in red, is actually an rotating conveyor belt. That slowly moves the dirt and the pebbles to the panel below. What you see on the green, that seemingly blocks the path of the conveyor belt, that vertical line, is a filter.

It moves like a garage door. You can ascend it or descend it. And leave a very small opening.

So the pebbles will be filtered out, staying on the conveyor belt, as the dirt is dispersed, separated, and drops down to the next line of conveyor belt.

Now the next 3 conveyor belts are different from the first one.

The 2nd line of the conveyor belt, contains holes. These holes are vacuum. Small enough for only the sand/flakes of gold can pass through. Once the sand and the gold is inside the conveyor belt, it is directed towards outside of the truck, where it is filtered again as the water escapes and the sand/dirt is washed out, but the gold remains. (As like the traditional method)

The purple circles are turbines. Like the blades inside a blender. The purpose is to flow the sand and the gold so it goes into the holes of the conveyor belt.

So it goes down to the 3rd belt, and the 4th, until it reaches the bottom. Each conveyor belt, as a dedicated garage door filtering. This is to filter out the pebbles. From big to small. You can adjust the height of the opening.

Eventually, ALL pebbles will reach the bottom below. AND some sand/gold flakes as well.

At which point, the blue bar at the very bottom, slides towards the piled up pebbles and sand. And pushes it towards the orange platform at the left most side.

Then the orange platform containing the pebbles, moves up, and then drops it down to the first conveyor belt. Again. (So a cycle until the sand/gold is fully extracted into the conveyor belts)

And once the salinity/purity of the water is detected by the sensors (that it is free enough for another dumping from the top) the user, (after removing the pebbles, which can also be pushed out all the way to the end, if the end has an opening and the platform is raised a little bit up for the blue bar to push on through) (the pebbles themselves can be also detected by the sensors by their weight. If it piles up too much, it should be removed before another round.)

then this way, LARGE VOLUME OF DIRT will be processed.

instead those slide pans and round pans people use their hands or shovel to clean up with.
