WebPartial melting is also linked to the formation of ores. Magmatic and hydrothermal ore deposits, such as chromite, Ni-Cu sulfides, rare-metal pegmatites, kimberlites, volcanic-hosted massive sulfide deposits are some examples of valuable natural resources closely related to the conditions of the origin, migration and emplacement of partial melts. WebForming alloys is an example of melting. Most alloys are made by mixing different metals in a molten state and then solidifying them. All metals have different melting points. This creates some difficulties in league formation. For example, copper melts at 1083°C while zinc melts at 419°C and boils at 907°C.
