Cane sugars are manufactured from sugar cane which is grown in tropical climates. Beet sugars are manufactured from sugar beet which is a root vegetable which can be grown in more temperate climates such as the UK.
There is no difference chemically between cane and beet sugar. They are both sucrose.

Molasses is a thick black syrup which is co-product from the processing of sugar cane into sugar.
Varying amounts of molasses trapped within the crystals of the Billington’s sugar products    are responsible for creating the different coloured and flavoured brown sugars.  For example Dark Muscovado sugar contains a higher level of molasses than Golden Granulated sugar.
Billington’s Molasses Sugar has the most natural molasses of all its sugars, and it’s perfect for adding colour and flavour to your Christmas Cake, Chocolate Cake or Marinades.
