Please be more specific, there are several answers to this.
1. Small portions could be called sediments, or pebbles.
2. What they could be made of are elements.
3. Metal material in rocks could be called resources.
Mineral particles in the soil are derived from the weathering of rocks and minerals.
Rocks have grains because they are made up of different mineral particles that have been compacted or cemented together over time. These mineral particles can vary in size, shape, and composition, creating the overall texture and appearance of the rock.
These small pieces are called particles. They can be broken down further based on their source - for example, particles from rocks may be referred to as mineral particles, whereas those from living things may be organic particles.
Those are called sediments. It is any sort of loose rocks and mineral fragments that are deposited in layers. They can either be transported by water, wind, ice, or gravity.

They are called grains and contribute to the texture of the rock.
The A horizon has smaller rocks and mineral particles than any other layers.....

A rock type that forms from particles of other rocks or the remains of plants and animals is called sedimentary rock. These rocks are created through the accumulation and compaction of sediments over time, which can include mineral fragments, organic materials, and other particles. Common examples of sedimentary rocks include sandstone, limestone, and shale. They often contain fossils and provide valuable information about Earth's history.
Sedimentary rocks. Sandstone is a common example of a sedimentary rock that is formed from the accumulation and cementation of sand-sized grains of mineral and rock fragments.
Conglomerates are among the group called clasticsedimentary rocks, those that are formed of cemented particles of other rock particles.
The particles of minerals or other rocks that make up a rock are called grains or crystals. These grains can vary in size and shape based on how the rock was formed and the types of minerals present within it.
Clastic sedimentary rock is composed of cemented particles of other rocks.
