To reduce the size of platinum ore, several processes are employed, including crushing, milling, and grinding. Initially, the ore is crushed into smaller pieces to facilitate further processing. Subsequently, it undergoes milling, where it is ground into a fine powder to separate the platinum from other minerals. Finally, additional methods like flotation or gravity separation may be used to concentrate the platinum content further.

Can physical weathering make a rock bigger?
Physical weathering is mechanical action which typically erodes rock faces. This invariably results in a smaller rock. Chemical weathering involves water absorption or other reactions. Mechanical heating and freezing can crack and fissure the rock, slightly increasing its size. In general, physical weathering is an abrading process, whether via water born sediment wearing away the rock, or wind blown particles sand blasting the rock, and these actions make reduce the rock's size.
What do geologists observe when looking at a rock's texture?
Geologists observe the size, shape, and arrangement of mineral grains in a rock's texture. This helps them infer how the rock formed and what processes it has undergone. Textures can range from fine-grained (small grains) to coarse-grained (large grains) and can provide valuable information about the rock's history.
What processes are used to reduce the size of the rocks?
Rocks can be reduced in size through several processes, including mechanical weathering, which involves physical forces such as freeze-thaw cycles, abrasion, and impact. Chemical weathering also plays a role, where chemical reactions break down rocks into smaller particles. Additionally, human activities such as mining and construction often employ techniques like blasting, crushing, and grinding to achieve desired rock sizes for various applications.
The surface of a break in a section of rock?
The surface of a break in a rock is called a fault. It occurs when there is movement along the break, causing the rock to shift position. Faults can range in size and can be caused by tectonic forces, weathering, or other geological processes.
What atom is bigger in size vanadium or platinum?
Vanadium is typically larger in size compared to platinum. This is because as you move across a period in the periodic table, the atomic radius generally decreases due to increasing nuclear charge, while moving down a group leads to an increase in atomic size. Vanadium is in a lower period (4th) than platinum (6th) in the periodic table, resulting in a larger atomic size for vanadium.
What generally happens to the porosity of sediments as they are turned into rock?
Due to the processes of compaction and cementation the pore spaces are generally reduced in size or in-filled with other minerals. This acts to reduce the porosity.
All changes in the original shape and or size of a rock body are called?
All changes in the original shape and size of a rock body are called deformation. This includes processes like folding, faulting, and shearing that can alter the appearance and structure of a rock.
What type of weathering affects the size of the sample?
Physical weathering affects the size of a sample by breaking down rocks into smaller pieces through processes like frost wedging, exfoliation, and abrasion. These physical processes can reduce the size of the sample by breaking it into smaller fragments.
Why doesn't the earth keep getting bigger?
The Earth's size remains relatively constant because any increase in size due to the accumulation of materials from space is offset by processes like erosion and natural movements of tectonic plates that reduce the planet's size. The Earth is in a dynamic equilibrium where these opposing processes maintain its overall size.
How do you reduce hand size for men?
When you reduce his penis size.

What process changes the space between the grains in a metamorphic rock?
During metamorphism, the grains in a rock can change in size due to processes like recrystallization, pressure solution, or plastic deformation. These processes can create new grains that are larger or smaller than the original ones, altering the space between them in the rock.
How can you reduce your head size?
There is no way to safely reduce your head size.

Is platinum heavy for its size?
yes it is
Does meat reduce in size when cooked?
Yes some meat will reduce is size . If u get meat from the store it can reduce in size but if u get your meat from a Boucher it's most like not do reduce in size . So when cooked it will stay the same size and not get smaller
Why is mineral texture an important aspect of petrography?
Mineral texture provides clues as to the origin of the rock particles and the processes which lead to the rock's formation. Texture would include the size and arrangement of the mineral crystals or particles found in the body of a rock.
