Overview of Melting Models

It is noted that the relationship between X and F is also important to distinguish the dynamic melting model from both the batch melting and the fractional melting models (Fig. 3). 

The slope in theX vs. F diagram for dynamic melting is l/(l-0) and is greater than 1 because 0 O 1. 

In this chapter, we focus on the batch melting model where melt maintains chemical equilibrium with solid, and stays with solid until the final extraction. 

Define F as the degree of partial melting, that is, the mass ratio of the melt over the initial mass before melting. The balance of the total mass and the mass of an element can be presented in Table 1.1. 

The concentration of the melt (Q) in equilibrium with the a multiple-phase solid is related to the concentration in the solid () by
