limits of the extraction procedure. The main advantage of this
procedure is that allows the selective separation of gold(III)
from wastes by a eco-friendly method which has acceptable
costs of implementation and exploitation. The procedure
described in this invention includes methodological details
for each work step and applicability limits for gold extraction
from electric wastes.

Description
The device is intended for heating a beverage by
exothermically dissolving calcium chloride in water in
optimal quantities. The device consists of two cups (a
bigger one, made of plastic, and a smaller one, made of
aluminum) placed one in another. The small cup is filled
with the desired drink. The space between the cups is
separated into two compartments (one for water and one
for CaCl2) by two perforated plastic lamellas, one fixed
and one mobile. By pressing a button underneath the
device, the mobile lamella rises and the lamellas’ holes
overlap, so the water enters the space with CaCl2 and the
drink warming begins. The device has a lid with which
can be covered and can be taken anywhere.
