Placer Mining Methods
The concentration of placer gold ore consists of a combination of the following three stages: roughing, cleaning, and scavenging. The object of concentration is to separate the raw ore into two products. Ideally, in placer gold recovery, all the gold will be in the concentrate, while all other material will be in the tailings.
Ore – Minecraft Wiki
An ore is any uncommon rock-type block used to obtain specific resources. Ore blocks are primarily collected for crafting purposes, such as for tools, weapons, armor, and redstone circuits. Refined ore can also be combined to create a block of the material's type. Most ores drop their resource when mined, and require a Silk Touch pickaxe to drop …

Concentration of ore
Concentration of ore is a step involved in the process of extraction of metal from its ore. Unwanted rocks and grit are eliminated from mineral ore in this process. Hydraulic washing, froth floatation process, magnetic separation and chemical separation are some of the techniques used for concentrating or purification of ores. Hydraulic washing:
What is the highest ore concentration on Minmus?
As I understand it ore maps are procedurally generated when you start a new saved game, so they will be different from save file to save file. The highest concentration I've found so far on Minmus is 10.97%, but it was pretty far from the equator, so I decided to build my refinery outpost on a nice respectable 10.4% spot on an equatorial ...
Understanding the Concentration of Ore: Methods
The method of concentration is chosen based on the properties of the ore and there are numerous methods available. Hydraulic Washing: This technique involves the use of water to separate ore from gangue. The ore is passed through a stream of water, which carries away the lighter gangue particles, leaving behind the heavier metal ore.
Ore concentrations
IOW, the best concentrations on Dres will be average or poor compared to what you usually find on Mun. The maximum concentration you'll find in any biome without > abundance setting is 15%. But I've never found more than about 11% once in a while. Usually, 8-9% is the best you'll see, and even that is fairly uncommon.
Gold processing
A large proportion of gold is recovered from refractory ores, and considerable skill is required in the design and operation of such facilities.

The particle size distribution of iron ore concentrate is given in the Table 1 and the chemical and mineralogical analysis are given in the Table 2. This concentrate was used for rheological test. At different concentration of slurry of concentrates, viscosity, shear stress profile i.e., flow curve, and yield stress are calculated.
Classification and mineralization of global lithium deposits …
After the initial brine concentration, the lithium-ion concentration in the pre-sun-drying pond can increase from 0.8–1.2 g/L to 1.0–1.4 g/L. Then, the brine flows to the second-order evaporation pond by gravity, where the brine depth is generally kept at 0.4–0.6 m, and the lithium-ion concentration rises to 1.2–1.6 g/L.
9.1.4: Natural Abundances of Elements
The economical concentration factor listed in the table above is the ratio of typical minimum economical ore concentration to average crustal concentration. For example, the average crustal abundance of chromium is about 0.01 wt %. Chromium ore can sometimes be profitable if it contains 30 wt % chromium. The necessary …
